There could be limits imposed by layers before PRPC, Web Server or Web Application server. For example the WebSphere IHS Web Server has a setting PostSizeLimit in the plug-in configuration that will limit the file upload size.
I'm doing great. Hope things are fine with you as well.
Thanks for you suggestion. It actually was a nice point. I tried attaching the file of 25 MB on UI I could observe "Internal server error" however when I closed and reopened the work object the file was attached to the WO.
Attaching the fiddler trace for reference.
Is there a browser session time out we can tweak in PRPC? If yes please help me with the same.
