I need a tool to view HTTP requests

Question

This is probably a browser extension or proxy.

For example, I open google.com and type in something and click "Search." And I want to see all the http-request parameters (e.g. method, domain, parameters, etc.).

Answer 1

Fiddler2

It will display all HTTP requests coming out of your computer. Coverage of all browsers and all other applications.

Answer 2

Wireshark

Wireshark is a free, open source package analyzer. It is used for network troubleshooting, analysis, software and communication protocol development and education. Originally named Ethereal, the project was renamed Wireshark in May 2006 due to trademark issues.

Answer 3

If you use Firefox, HttpFox is great for this. Can check all GET / POST contents, headers, etc.

Answer 4

If you use Firefox, Live HTTP Headers is a great addition:

Answer 5

If you are not using Windows, ignore this answer.

I used Wireshark, but recently I started using Microsoft Network Monitor , which is also very nice. If you have your own protocol (which I know there is no OP), it is very easy to write your own protocol parser, which is a great PITA with Wireshark.

Answer 6

Here is one and very cool:

web-sniffer.net/

Answer 7

httpwatch HTTP Viewer and HTTP Sniffer for IE and Firefox

Answer 8

Firebug The Net section contains some relevant information, but this is more response time / load time. However, headers are present.

Answer 9

I use Live HTTP Headers and Firebug plugins for Firefox to see the current data coming from the website.

If you're just looking for what might be in it, look at the w3c standard here , the original RFC, or the updated RFC .

Answer 10

Firebug

If you are going to monitor and debug only in Firefox.

Simple, lightweight, clean and easy to use.

Answer 11

Sometimes a proxy server is not a good solution, because it affects the connection settings.

Check out HTTP Debugger Pro .

I support both HTTP and HTTPS connections for all browsers, including Chrome.
