We've got a website which has been running for a few years now. One of our customers has just started having an intermittent problem. Looking at our iis6.0 logs the service works correctly when they have a user agent beginning "mozilla/4.0+" but fails when the user agent begins "mozilla/5.0+". The particular customer only started having this problem on Wednesday.
Does anyone know the browser/upgrade which changes the 4.0 to 5.0?
The actual problem caused is that an "&" in a url parameter list is being encoded as "&". Anyone seen anything similar?
We have other users sending from browsers with the 5.0+ user agent without trouble.
Sorry about the tags but don't have the rep to create new ones.
Thanks in advance, Patrick
Edit: hi Viper_sb,
It is most probably a custom script (I'm primarily a c++ developer so don't really understand). Our site services requests from other customer developed sites, this one was done in Java script as far as I know.
we're actually getting a variety of user agents (presumably depending on which of our customers customers is accessing the service), here's a few: Mozilla/5.0+(Windows;+U;+Windows+NT+6.1;+fr;+rv:188.8.131.52)+Gecko/20100701+Firefox/3.5.11
