There appears to be a bug in IE (and possibly in squid - used in the
RouterOS proxy server). Firefox is reported to work fine with hotmail,
therefore the suspicion on IE – this is not verified.
While there is no patch for squid which will solve this problem, the only
solution is to not use transparent web-proxy for hotmail pages.
Here are some suggestions:
There are 2 ways to detect hotmail requests (none of them is tested by us):
bad news: you have to wait for a squid/IE/MSN fix. the workarounds mostly work, but are only a temporary fix because they simply make requests to msn go directly, not through proxy.
good news: the new web proxy (‘the proxy’) in 2.9 works fine. if you use that, or use it as a parent proxy for 2.8 - no MSN bug.
Thanks for working on getting this fixed. We have had some customers complaining about problems with MSN (I’m assuming this is similar to the problem with Hotmail). Which package(s) contain this update (or, which packages needed to be updated to get this fix)?
