Excluding webresource.axd worked for me. I was using IIS compression and had the same problem after upgrading to 4.4.1. from 4.4.0.

Add webresource.axd to the Excluded Paths. Should look like:

install/install.aspx
linkclick.aspx
webresource.axd

Select Update under Compression Settings (Not the Host Page Update). Then select restart application. Then selectHost Page Update. Clear your application and browser cache.

I added the webresource.axd to the excluded paths (just like the previous examples) and clicked the 'Update' specifically for the Compression Settings (doh!) and that took and set.

Then I clicked 'Clear Cache' above, even did the 'Restart Application' (at bottom of page), walked away for a bit.

Came back and still didn't work.  As I was putting together this post I thought I'd check it again and wouldn't you know it...it works.

I guess the lesson today is - Patience

We had some issues with compression in 4.4.0, so we made a number of changes in 4.4.1 that should fix all or most of them.  The main changes made were this:

  1. Disabled compression by default in 4.4.1 installs (note though that if it was enabled in 4.4.0, upgrades will still be enabled)
  2. Changed the exclusion path comparison so it handles the scenarios mentioned in this post (without removing the w from the webresource.axd).
  3. Include webresource.axd by default in Compression.config

FYI: For those who have asked - webresource.axd is the file that contains the javascript neccessary to support the ASP.NET postback architecture

Now, for those that still experience issues with 4.4.1 after upgrading you need to remember this.

  1. The Compression.config file in the \Config folder which is distributed with the app is copied to the root on install (not upgrade), so you may need to manually update the Compression.config file in the root of your app to make sure it contains the appropriate values.
  2. You will need to clear the server side cache - if you can make sure that your application is restarted to make sure all cahed objects are cleared.
  3. If you had downloaded a corrupt file into your browser cache - it may need to be cleared, so clear your browser cache.

Please bear with us as we learn how to handle these compression related issues.  Remember, that compression is an option to improve the performance of your application.  If you cannot get compression to work in your scenario, then you should disable it completely in your web.config by commenting out (or removing the entry).

For anyone just discovering the issue, this is a list of exclusions pulled together from various threads about various issues. The blue ones are default in 441.

I also noticed that "imagechallenge.captcha.aspx" was in a fresh 441, but not in the upgraded 441 so people might want to check for that one as well.

Excluded Mime Types:
image/gif
image/jpeg

image/png
application/zip
application/x-zip-compressed
application/x-gzip-compressed
application/x-compressed
application/octet-stream
application/pdf

Excluded Paths:
install/install.aspx
linkclick.aspx
webresource.axd
imagechallenge.captcha.aspx
