Thanks for looking into this.

I've only done very cursory testing with nginx so far, but since that's
quite a slick server I'd very much like to support it* without users like
yourself needing any hacks.

Is it possible that the server is sending extra data to the FastCGI backend
and expecting the script to check some meta-data in the form data? Just a
stab in the dark really.

If you are able to get the complete POST'd data from request.post_data(),
dump it to a file and send me it (off-list if you prefer) I can take a look
at it.

Sorry I can't help more.

Cheers,
Darren

* There were rumours of a multiplexing FastCGI module for nginx, which would
be very very nice to get my hands on, if that ever surfaces.
