I've got an IIS server which runs my standalone CGI EXE application (no ASP or similar)
When switching from IIS6 to IIS7 I frequently begin getting one single "S" character as input, from IIS7, to this exe program, instead of the actual payload from the end user browser.
This only happens when https is used, and it only happens "sometimes" (I cannot see any "system" in that, but some users are more "hit" than others)
Any ideas why the IIS7 payload *sometimes* is replaced with one single "S" character, when presented to the CGI standsalone program, by the IIS7 server, driven by a user https request?
