Hello, I'm a new user.

I've been using the hostname replacement using fiddler.

I was trying to update my Qt installation but the maintenance tool was defaulting downloads from slow mirrors. I was changing the hostname to faster mirrors.
The hostname replacement was working and the download speeds are improved (task manager shows Fiddler maxing the download speeds).

The problem is fiddler keeps spamming the link (see first attached picture) and even if one of them finishes downloading, it says that the session was aborted so the qt maintenance tool doesn't get the requested file and it gets stuck in a loop.

This only happens when it's downloading a big file. Small files (<10MB) gets confirmed to be downloaded in the qt maintenance tool.

I think it is because since the smaller files downloads right away, it gets registered as a response on the qt maintenance tool before it requests for another but since the bigger files are slower to download, the tool doesn't get a response right away so it spams requests, when the earlier requests finish downloading, the tool doesn't accept it. So the result is Fiddler keeps spamming requests even if the earlier request finish downloading.

How do I fix this?

Turns out out fiddler buffers content before forwarding it to the app. I just had to enable streaming mode :>
