We're currently trying to debug an issue we have whereby our file upload form (from a c'# .net web application) works with the .net2.x/32 bit version of our application but no longer works with the .net4.x/64 bit version, the request times out without connecting to the webbroker.
GET requests work fine on both versions, it just seems to be the 64 bit POST request we have an issue with.
I've traced the process as far as I can but lose track once it gets to cgiip, with the logging level turned up to 99 I can see where it gets to in cgiip but there's no indication of why it is failing.
I will be out of the office until Monday August 19th, 2013.
In urgent cases please contact Peter Rietdijk, Wim Keuker or Romano Wattimena.
