What can you do using Fiddler?

Using Fiddler you can

• See what requests are sent from browser to server (you are not limited just to browser, any application that is using HTTP protocol can be monitored)
• See what responses are returned back
• See data contained in the request
• See data contained in the response
• See if processing of request failed or succeeded
• Create requests and send them to server
• Intercept a request, modify it, re-play it again
• Create collection of requests that can be reused later
• Visualize the request and response using many different inspectors
• Decrypt encryped HTTPS traffic between and see unencrypted data that flow between your browser and server
• See how long it takes to process a request on the server
• See how long it takes to send a request and receive the response
• See a sequence in which the requests were sent
