We have a user try to post a 16 MB Tableau file (.twbx) on SSRS 2005 server. The process was failed with error "HTTPException: Maximum request length exceeded". The user can post a 13 MB file without problem. The parameter maxRequestLength in machine.config file on the host where SSRS is installed has been increased from 4 MB to 65 MB, but it doesn't seem to help. Any suggestions? Thanks.
