Below is the dump from debug that shows that it is returning successfully, however it dumps html code:
SWF DEBUG: Global Post Item: CSR_TO_ATTACH=1904,ASPSESSID=jmvoqt2ncwnq2i45zyzi3a55,AUTHID=150EE0CDB041FE55F32B1E5D53BCB81DFCA4608F685DB9E82DA521C1C0225DCF01202B0B9EF101546D4AEF7CBCEDC19F6AD9A58C8223B78D265E2650F914F3CE7EC44EA19DE37B91AD5D260AD8A743B8=undefined

etc.
etc.

I have implemented the requested changes in the Global .asax, however I decided to implement them in a HTTPModule instead. Works great in my test environment, but not on the production server.

You can see that I am posting the session goods, however it still chokes.

Any ideas, recommendations?
