Dear John,
The option "gzip_static" requires, that the files to be delivered are gzip
compressed in the file system. In order to have "gzip_rerfresh" working
(automatically re-compress the file when the version has changed) requires
that the server has write permissions on the .gz file and that "gzip_cmd"
points to the gzip program.
Below is something some data from a life site (openacs.org) having
static gzip delivery enabled with a snippet from the config file.
There is no extra filter necessary to get this working.
best regards

I’m struggling a bit to get naviserver to gzip static content (.js
and.css). ADP gzipping is working.
According to the docs, it’d seem that all I need to do is enable all
the fastpath config stuff below, and it’d work, but that’s not doing
the trick. Perhaps there is additional fast path configuring to do to
enable certain directories?
According to this code by Daniel Clark, a fast path filter is needed
to make this work, but it seems that (a) his code may not be current
and (b) his filter doesn’t work because he doesn’t supply the other
dependent functions his code calls.

I’ve looked at the fastpath.c/fastpath.tcl as the docs indicated, but
was not illuminated.
I probably just don’t know where to look, but after about 2h of
banging on this, I thought I’d ask for help….
