Fiddler is a powerful tool for web developers and testers. It allows you to intercept, inspect, and modify HTTP and HTTPS traffic between your computer and the web server. The Web Sessions List is one of the key features of Fiddler, which provides a comprehensive view of all the HTTP and HTTPS requests and responses. In this article, we will explore some tips and tricks to make the most of the Fiddler Web Sessions List.
Filtering Web Sessions
The Web Sessions List can quickly become overwhelming when you are dealing with a large number of requests and responses. Fortunately, Fiddler provides several filters to help you quickly find the sessions you are interested in. You can filter sessions by URL, response code, content type, and more. To apply a filter, simply type in the filter box at the top of the Web Sessions List.
Sorting Web Sessions
You can sort the Web Sessions List by any column by clicking on the column header. This is especially useful when you want to group sessions by URL, response code, or size. You can also customize the columns that are displayed in the Web Sessions List by right-clicking on the column header and selecting “Choose Columns”.
Inspecting Web Sessions
To inspect a web session, simply click on it in the Web Sessions List. This will open the Inspectors tab, which provides a detailed view of the request and response headers and body. You can also use the Inspectors tab to modify the request or response before sending it back to the server.
Comparing Web Sessions
Fiddler allows you to compare two web sessions side-by-side. This is useful when you want to compare the differences between two requests or responses. To compare two sessions, simply select them in the Web Sessions List, right-click, and select “Compare Sessions”.
Exporting Web Sessions
You can export the Web Sessions List to a variety of formats, including HTML, XML, JSON, and CSV. This is useful when you want to share the session data with other team members or import it into another tool. To export the Web Sessions List, simply right-click and select “Export Sessions”.
Fiddler allows you to set breakpoints on specific requests or responses. This is useful when you want to pause the traffic flow and inspect or modify the request or response before sending it back to the server. To set a breakpoint, simply select the session in the Web Sessions List, right-click, and select “Set Breakpoint”.
Automating Web Sessions
Fiddler provides a powerful scripting engine that allows you to automate web sessions. You can write scripts to modify requests and responses, extract data from responses, and perform complex operations on the session data. To create a script, simply select “Rules” from the Fiddler menu and click “Customize Rules”.
The Fiddler Web Sessions List is a powerful tool for web developers and testers. By using the tips and tricks outlined in this article, you can easily filter, sort, inspect, compare, export, set breakpoints, and automate web sessions. With Fiddler, you can gain deep insights into the HTTP and HTTPS traffic between your computer and the web server, and develop and test web applications with confidence.
