Q: I like to navigate around a site then do a "search" for a text on all the
logged request/responses. I was curious if Fiddler automatically decompressed gzipped responses during search?
A: Fiddler does not decompress during searches by default,
since it would need to keep both the compressed and decompressed body in memory
(for data integrity reasons).
In current versions of Fiddler, you can tick the "Decode Compressed
Content" checkbox on the Find dialog.
Q: The HTTPS protocol was designed to prevent
traffic viewing and tampering. Given that, how can Fiddler2 debug HTTPS
traffic?
A: Please see the topic Decrypting HTTPS
traffic with Fiddler2.
Q: I have another problem.
A: Check the Known Issues or
ask in the community!
