Compression of HTTP Requests
- Web server responses can be compressed through setting a property on
the Web Profile. This works well!
However, whenever you leave a PIA page it's data content (or Form
Data) is ALWAYS sent via a POST request to the web server. This is
so the session state object can be kept up to date with any changes.
This HTTP request object is not compressed. Even if you do not
change any values on a page ALL of it's data will be sent back with
the next Request.
I am 99% certain that in Tools release 8.14 either the requests were
compressed and/or only changed form data was sent back in the Request
object. We did extensive testing of this just before we rolled out
to 1000 users worldwide and we would have noticed if there was a
problem. Something has changed since we did this testing to cause us
severe performance problems on poor networks. Could be IE browser
release, switch from NT to XP, Weblogic version, PeopleTools
version? I don't know.
My question to my friends is "Do you know of any way of compressing
the client requests or know of anyway of preventing unchanged data
from being included in EVERY roundtrip?"
