You could subclass WAKom and start with something like:
| response gzip stream |
response := super convertResponse: aResponse.
response fieldAt: 'Content-Encoding' put: 'gzip'.
gzip := GZipWriteStream on: (stream := RWBinaryOrTextStream on: '').
gzip nextPutAll: aResponse contents contents; close.
^ response contents: stream reset
This code does not check if the user-agent supports compressed
responds, most todays user-agents do that anyway and one could add it
However I doubt that this will make the web-application any snappier,
I guess it is even much slower because the stream has to be copied to
a compressed one. After all the XHTML of Seaside is already quite
dense, there are no unnecessary spaces as with most other frameworks.
It is a bit trickier and requires some modifications to Seaside if you
want to directly stream you answer into a compressed stream, tough it
should be possible.

I never felt the need to do anything like that, the bottleneck is
usually the persistency backend or the domain-model itself, not the
