I've got a situation where SP is recording an action of getting a PDF file as a WebFormGet. When I record this action I can see the header:
Accept-Encoding: gzip, deflate
And when I playback the script the same header information is being sent, but SP calls out a warning message saying:
WebEngine: 77 - Compression method not accepted, no decoding performed!
Now I've modified the profile to change this from a warning to an information status, but I'm curious why this might occur when all the headers on playback look identical to the headers from the recording.
