[Mono-list] ASPSESSION cookie not stored

[winzen at online.de]

Hi everybody,

i encountered a serious problem while trying to migrate a 
ASP.NET application from IIS to Mono (mod_mono/apache).
The application has to store some objects in a session. 
The objects are not serializable so i have to use InProc session state.
With MS.NET and IIS this is working in all browsers (IE6, Firefox, Opera).

When i run the application with Mono
(Server-Environment: Apache/2.0.54 (Debian GNU/Linux)
 DAV/2 SVN/1.1.4 mod_mono/1.1.10.1 PHP/5.0.5-Debian-0.8~sarge1)
there is a problem with session handling in IE6.

Looking into the trace output i could verify that the ASPSESSION 
cookie is not stored at all. This only affects the combination 
mod_mono + IE6! All other pairs (e.g. Firefox + mod_mono) are working. 
My IE6 uses this User-Agent entry:
Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; .NET CLR 1.1.4322)

Our customer uses IE so simply not using it is no option.
Does anyone have a good solution to this problem?

Thanks in advance,
Jochen Winzen
