Status: Verified
FACT(s) (Environment):
Progress 9.1x
SYMPTOM(s):
The wsial.dll messenger is locked up and the session hangs.
Use Microsoft IIS Web Server
Only Limited size of data can be read in each message using WSISA.DLL
CAUSE:
When using the WSISA.DLL in WebSpeed running on the Microsoft IIS Web Server, there is a limit on the size of data it can read in each message. This only happens with the WSISA.DLL and causes the messenger to lock up and the session to hang.
FIX:
IIS has a property in the metabase called UploadReadAheadSize.
This value determines the size of the request that IIS will take (for security).
The value of this property needs to be increased.
