Hello,
After discussing the topic of compression here (4.4.1 serious problem - WebForm_PostBackOptions is undefined), I thought that everything was solved and working.
Unfortunately, on my new clean-fresh DNN 4.4.1 install (same with my dev, an upgraded from 4.3.7 --> 4.4.0 --> 4.4.1), I have the following bug: impossible to download a file deposited in a repository if compression is ON. In such case, I click download, and nothing is happening (the window for downloading appear, but nothing happens). I found a "general exception" and "page load exception" in the log viewer. My compression parameter are the following:
and my exceptions are the following:

I have logged it into Gemini, since I reproduced the problem on 2 different systems (sorry if it is not a good idea, but this is not the first time that someone ask me to log something into Gemini).
If I remove compression, it works without any problem. I also tried to change the file in the repository, no success. Conclusion: I am not working with compression OFF, which is a pity, because compression speed up the site, it's incredible !!!
