You can beat such restrictions by browsing using proxies. Proxies protect your identity online by concealing your IP address and presenting its IP instead. As a result, any website that had put in place systems to deny you access can’t block you since they can’t identify you.

Not everyone, however, uses proxies for data mining for their businesses. Some use them for privacy, anonymity, and cybersecurity, among other uses.

Various types of proxies have, therefore, been developed to cater to each of these tasks. Each category has features that make it suitable for one purpose and not so ideal for other tasks.

Proxies can, therefore, be put in different categories depending on the criteria used.

1. Based On The Origin Of The Proxy’s IP

a. What is a residential proxy?

Internet service providers assign an IP address to all their customers. The IP address for each device used to access the internet is unique and can be used to identify the browser location.

Companies that provide proxy services often reach out to individuals asking them to allow them to use their IP addresses for proxies. This is, of course, at a fee.

If they agree, the ISP-provided IP address is allocated to proxies that clients can use to access websites. These are called residential proxies.

When you use a residential proxy, you are using someone’s IP address. Therefore, websites and other programs perceive your device to be browsing from that person’s residential address.

Residential proxies are divided into:

Rotating residential proxies: IP address changes at regular intervals. You negotiate with the service provider on how often you want the IP to change.

Static residential proxies: You use the same IP address for an extended period. They are much faster than rotating proxies yet still as secure and reliable.

b. What is a data center proxy?

For this type of proxies, the IP address comes from data centers. The data centers, in this case, are servers dedicated to the administration and management of proxies. Due to the specialized software and broad bandwidth of these servers, data center proxies are fast.

This makes them ideal for use for tasks that use bots such as web crawling. Proxies for sneakers are mostly data center proxies.

Unfortunately, some sites also identify data center proxies based on the speed of the traffic. For example, a real person would take a few seconds or minutes to buy an item from a site. But a sneaker bot using data center proxies can make the same transaction in microseconds.

When some sites note such speeds, they block the IP address for bot-like activities. This makes data center proxies less reliable for such tasks.

Date center proxies are further divided into Secure socket Proxy (SOCKS) and Hypertext transfer protocol (HTTP) proxies.

2. Based On The Protocol Used

a. What is an HTTP proxy?

You’ve probably noticed many URLs have an HTTP portion. This means that the site uses the hypertext transfer (HTTP) protocol.

This protocol works such that your browser sends a request to the website’s server in the form of a URL. The server then processes the request and responds with the information you requested.

Usually, the traffic is direct. But for your online privacy, you can add a proxy that uses the HTTP protocol as an intermediary between your browser and the site’s server.

HTTP proxies are more ideal for browsing the internet. Most proxies are, therefore, HTTP proxies.

b. What is a SOCKS proxy?

These proxies use the Secure Socket (SOCKS) protocol. With HTTP proxies, the website server must also be using the HTTP protocol for it to form a successful connection. This is a limiting factor in HTTPS proxies.

SOCKS proxies, on the other hand, can form a connection with various types of network protocols. They are, therefore, more flexible and versatile.

The main disadvantage with SOCKS proxies, however, is this. They do not secure your traffic data as it is being transmitted between your device’s browser and the website.

Final words

Proxies can be divided based on a variety of criteria. For instance, you can categorize them based on the level of anonymity, the usage method, the duration you can use one IP, etc.

These criteria, however, result in too many and fragmented groups of proxies. Some of the resultant groups can be categorized under some of the groups discussed above.

The criteria we have used above gives you a broad classification of proxies. You can delve into each category individual for more details and further kind.

Professional proxy-providing sites have knowledgeable and capable customer service providers that can offer you clarification where you may be confused.

The post Wireless Communication Technology and its Applications appeared first on Tech India Today.

The full form of the HTTP is Hypertext Transfer Protocol. HTTP (Hypertext Transfer Protocol) is the most popular and widely used web-based Application layer protocol based on the conceptual model of the Internet protocol suite. In the OSI model HTTP protocol, it belongs to Layer 7 called the Application layer.

HyperText Transfer Protocol (HTTP full form) transfers and combined the hypermedia information in World Wide Web (WWW). HTTP is the Standard protocol for Web Browsers that helps users exchange hypermedia information from one place to another through the Internet or World Wide Web (WWW).

The Hypertext Transfer Protocol (HTTP full form) helps to communicate hypermedia information between clients and servers.

HTTP Protocol Works based on Request-Response protocol between Clients and Servers, The Client may be a web browser or User-Agent, and the server may be a Web server or any other host, etc.

HTTP was initiated at CERN in 1989 by Tim Berners-Lee and also the inventor of the World wide web (WWW) HTTP/1.1 first documented in RFC 2068 in 1997.

HTTP Working Group was formed in 2007 and refined the HTTP/1.1 Specifications. In the year of 2014 June month, The Working Group (WG) Release six updated specifications.

• Message Syntax and Routing – HTTP/1.1 (RFC 7230)
• Semantics and Content- HTTP/1.1 (RFC 7231)
• Conditional Requests- HTTP/1.1 (RFC 7232)
• Range Requests- HTTP/1.1 (RFC 7233)
• Caching- HTTP/1.1 (RFC 7234)
• Authentication- HTTP/1.1 (RFC 7235)
• HTTP/2 was published as RFC 7540 in May 2015.

1. HTTP Version released Year

• 1991 version 0.9
• 1996 version 1.0
• 1997 version 1.1
• 2015 version 2.0
• 2018 version 3.0

2. HTTP (HTTP Full Form is Hypertext Transfer Protocol) Request-Response Architecture (purpose of HTTP protocol or use of HTTP protocol:

If the user requests the query from the Client (Browser), The HTTP Protocol takes the information and sends it to the server (webserver), If the information is available on the server, the server responds as per the user’s request or if the information is not available in the server, the server returns the information source as not found in the server as per the user’s request.

HTTP protocol Is the media between the client and the server for exchange or transfers the hypertext or hypermedia like any Text, Audio, video, any other data files, etc.

3. HTTP Methods or HTTP Verbs:

HTTP Defines Some Methods Sometimes we referred to HTTP Verbs

All HTTP Methods Names are Case Sensitive is

• GET
• POST
• HEAD
• PUT
• DELETE
• OPTIONS
• PATCH
• TRACE
• CONNECT

4. HTTP GET Method:

HTTP GET Method is the most generally used HTTP method for requesting data from a specific source; it means it retrieves the data from the web server using parameters in the URL place.

The HTTP GET method can transfer a limited amount of data from the client to the server because data will send in the header.

The request parameter would be a string. The query string written in the URL is a key-value pair. The GET Method is used for requesting data from a specific source.

GET is a method to send a limited amount of data because data can be sent or transferred in the header by passing URL parameters called query strings (key-value pairs).

The GET request method is not secure because data is visible in the URL, and users can bookmark the requested data in the browser.

GET Method requested data is idempotent or called a safe Method, which means the second request is rejected or fails until the response of the first request is delivered.

The GET method is adequate and used more than other HTTP methods like a post.

5. HTTP POST Method:

In the HTTP POST method, the request data will be a significant amount, because data send in the message body. POST Method is used to create a new resource on the server.

The POST method is secure because the POST method request will not be visible in the header, i.e., the URL’s Query String.

You can’t bookmark the HTTP POST request.

The HTTP POST method request will be non-idempotent. For example, If You called or Send the same POST Request Multiple times or N number of times, You will get Multiple new resources on the server. It sends the data to the server (secure data compare to the GET Method) for creating or Updating the data.

The POST method request is adequate and used less than the Get method.

6. HTTP HEAD Method:

HTTP HEAD method is nearly similar to the GET Method but without the response body.

HTTP HEAD Method is used to get Response status only and also receives the header’s information from the web server with nobody (Records).

HTTP HEAD Method is used to find whether the source exists in the server or not by the Analysis of Response status or Response Header information, for example for Testing, whether the hyperlinks are valid are not.

The Response Meta Data or Information in The HTTP Header of the HEAD method is identical to the Response Meta Data in The HTTP Header of the GET Method. The difference is that the response of the HEAD Method Request doesn’t contain the message body.

7. HTTP PUT Method:

HTTP PUT Method is used for Sending the data to the webserver to Create a new record or update an existing record.

The Difference between the HTTP PUT and POST Methods is That the PUT Method is idempotent, and the Post Method is non-idempotent. For example, If You are requesting the same HTTP PUT method multiple times on the server, The HTTP PUT method produces the same results. Data will not change; it just overwrites the same data because it is idempotent.

If the HTTP Methods don’t modify or change the resource or data in the server Those methods are called safe methods, PUT and POST methods are unsafe methods because data can be modified in the server.

8. HTTP DELETE Method:

The HTTP DELETE Method is used to Delete the resource or data in the server.

If You request or call the same DELETE Method request Multiple times, The first Request of the DELETE Method Deletes the data or information and the response will be 200 (OK) or 204 (No Content), Remaining request response will be 404 (Not Found), the remaining request responses are different from the first request, there is no change of data in the server because original data already deleted, so DELETE HTTP Method is Idempotent.

9. HTTP OPTIONS Method:

HTTP OPTIONS Method specifies the communication options for the target resource (server).
It Means The HTTP OPTIONS Method is used to find out HTTP Methods and the web server will support the remaining Options.

10. HTTP PATCH Method:

HTTP PATCH Method can modify the data, It Means the HTTP PATCH Method request changes the Resource information (Not the complete Information resource).

11. HTTP TRACE Method:

HTTP TRACE Method was designed and used for diagnostic purposes. The HTTP OPTIONS and TRACE Methods should NOT have side effects.

HTTP TRACE Method used For debugging, developers can see what changes have been made after debugging.

12. HTTP CONNECT Method:

The HTTP CONNECT Method Creates a Point-to-point Communication Between Two Devices, HTTP CONNECT Method can be used to create a tunnel to the Secure Device or Machine.

HTTP tunnel or HTTP Tunneling Creates a Data or communication Network between two Devices.

The most General form of HTTP tunneling is the standardized HTTP CONNECT method.

HTTP CONNECT method is used to access Websites That use Secure Sockets Layer (SSL) or HyperText Transfer Protocol Secure (HTTPS). The secure connection is established by using the HTTP CONNECT Method.

13. HTTP Safe and Unsafe Methods:

GET, HEAD, OPTIONS, and TRACE methods are Safe HTTP Methods, Remaining HTTP Methods like POST, PUT, DELETE, CONNECT, and PATCH.

14. HTTP Idempotent and Non-Idempotent Methods:

POST, CONNECT, and PATCH these three HTTP Methods are Non-Idempotent Methods, Remaining HTTP Methods like GET, HEAD, OPTIONS, TRACE, PUT, and DELETE are Idempotent Methods.
