Problems with secured IE

[Alexandr Sergeyev]

Ian, 

You're forcing Gzip encoding to all clients even if they do not send "accept encoding" request header. You even don't send content-encoding  in the answer which is also incorrect. Even if client says "I do not support gzip" you are sending it. 

Other warnings about your server behavior are her:

Please note, that if you'd like to force gzip to some IE6 and other situations when client would understand gzip answer but did not send Accept-Encoding you may read these notes from Velocity 2010 presentation:

Subject: Problems with secured IE

Hi All,

I'm webmaster of a number of websites, and several people have reported 
that they are having problems using some of my sites

They are all using versions of IE that are in libraries or large 
corporate installations and thus heavily secured.

One gets the following error:

"Internet explorer cannot download coachmaster.htm from bobgriffiths.com.

Internet Explorer has not been able to open the internet site. The
requested site is either unavailable or cannot be found. Please try later. "

There appeared to be no break in service at the time - visitors arrived
a few minutes before and after the time. No error in the log.

Three others are having problems when using the long polling module. If
they are using a secured version of IE they get repeating messages.
Normal IE and all other browsers I have tested work just fine.

Two others report that they are getting a screen full of characters.
This appears to be that the browser has claimed it can handle gzip
but actually attempts to display the gzipped file. I have disabled
gzip on the site and we shall see if this is a solution.

The common elements are:-
all the users are on secured machines on corporate sites.
only one of my customers is effected.
the server is nginx 0.7.67
The pages are processed by php via fastcgi.

Does anyone have any ideas what is happening - and what I can do about 
it. "Cannot reproduce" is wearing a bit thin :)

Regards

Ian
