2009/08/18 - Apache AxKit has been retired.

Hi,

(as far as i can tell after a quick peek at the code and some debugging)

It looks like there is a bug w/ AxKit::run_axkit_engine() and/or
Apache::AxKit::Cache::_get_stats()

run_axkit_engine() wants to create a .gzip cachefile when AxGzipOutput is
off.

When AxGzipOutput is off the .gzip file is never made and _get_stats() 
returns w/ !$self->{file_exists} effectivly disabling delivering cached
copies.

With AxGzipOutput enabled both files are created and appropriate cached
copies
are delivered as expected.

I haven't decided for myself a best fix except for just enabling
AxGzipOutput.

So, I reran hello/bench.pl w/ AxGzipOutput On and sped axkit up quite a
bit.

attached are some diffs and a couple of 1 sec bench.pl runs.  Would be
interesting to see how axkit compares now?

Thanks,

Ed
