Rosetta Stone online not working #151

Closed thetmtech closed 6 years ago

thetmtech commented 6 years ago

Since we installed Cloudveil on our PC, there are parts of Rosetta Stone that do not load. We can access Phrasebook and Extended Learning, but not My Lessons.

I'll try to document the problem and get back here.

The URL that gives an error is https://tracking.rosettastone.com/users.

A sample of request headers from calls to that URL.

My first guess is that the filter is mangling request payload because it looks like it's a binary payload.

Content-Type of returned content is text/xml

It appears the problem is that FilterCore is removing Content-Encoding: deflate from the headers of the request. Removing it from the ForbiddenHttpHeaders does not seem to have any ill effects. Perhaps related to #103?

kfreezen commented 6 years ago

I believe this is fixed.
