Is there a plugin to decompress Microsoft xpress compression ? Fiddler can decompress this protocol

Thanks Martin

Xpress isn't a protocol, it's a compression algorithm.

If you tell us which network protocol is using Xpress to compress data, then we can tell you if Wireshark supports that.

Windows WSUS uses xpress to compress HTTP data

I suspect that the compression used would be indicated in a header or mime-type. Can you share a capture that shows this?

I don't see anything for this in the current code so it would need a Bugzilla item raised along with a capture containing Xpress compression.
