If-Modified-Since header is not set for dynamicly compressed static files

[dave@…]

I've noticed that the google feed fetcher seams to query feeds on the sites I host a lot, and always returns 200. Initially I thought this was a problem with the fetcher not submitting enough header information to generate a 304 if nothing had changed. However I sniffed the packets for this transaction and google is presenting If-Modified-Since

Lighty should send 304 not modified because the Last-Modified date on the resource is before the if-modified header.

The file in question is a static file generated by MT.

This is a bug in mod_compress.

As soon as you set the compress.cache-dir it will work as expected.

This might be fixed in changeset [1046]

Changeset [1046] + [1057] fixed the problem.
