Post requests are a type of dialog between the client application and the server. They are designed to transfer and add data to a remote resource. Therefore, these requests have a special container for the transmitted information, called the request body. The body of the post request and its headers are transmitted invisibly to the user using the site using a browser.

Instructions
Step 1
Modern browsers contain tools for web developers to get some information about the post requests being sent. If you need to see the headers of just a couple of requests, using them will be easier and faster than other methods.
Step 2
If you are using Firefox, you can use its web console. It displays the request headers and the content of the cookies transmitted. To launch it, open the browser menu, click on the "Web Development" item and select "Web Console". In the panel that appears, activate the "Network" button. Enter the method name in the filter field - post. Depending on your goals, click on the button of the form sending the required request or refresh the page. The console displays the submitted request. Click on it with the mouse to see more details.
Step 3
Google Chrome browser has powerful debugging tools. To use them, click on the icon with the image of a wrench, and then open the item "Configuring and managing Google Chrome". Select "Tools" and launch "Developer Tools". In the toolbar, select the Network tab and submit your request. Find the required request in the list and click on it to study the details.
Step 4
The Opera browser has built-in developer tools for Opera Dragonfly. To launch them, right-click on the required page and select the "Inspect Element" context menu item. Go to the Developer Tools Network tab and submit your request. Find it in the list and expand it to examine the server headers and responses.
Step 5
Internet Explorer 9 contains a kit called F12 Developer Tools that provides detailed information on executed requests. They are started by pressing the F12 button or using the "Service" menu containing the item of the same name. To view the request, go to the "Network" tab. Find the given query in the summary and double-click to expand the details.
Step 6
The Chrome and Internet Explorer 9 browsers contain built-in tools that allow you to examine the submitted post request in full detail. For full details use them or Firefox with the Firebug plugin installed. It is very handy for frequently examining queries, for example, when debugging sites.
Step 7
If you want to see a request sent by a program other than a browser, use the Fiddler HTTP debugger. It works as a proxy server and intercepts requests from any program, and also provides very detailed information on their headers and content.
