"invalid header" error by https access

[Dominik Schmid <dominik_schmid@xxxxxx>]

Hello out there

When i try to access a https page with the  internet explorer and i'm 
currently not authorized, i get the invalid header error.
The request in the squid access.log shows, that the request is being 
sent in http protocol and not htttps...

Then when i try again to connect to the page, i am authorized and it works.
Firefox works fine without this error.

Squid version is a daily snapshot of the 2.5 version 10.

IE-Version is 5.5 or 6 SP1

I'm very happy for any ideas.

Thanks Dominik
