Hi Nick, 

To test it futher I gzipped a local file and posted it apache using 'ab' (I had 
set the content-encoding header as well')
Even then I see the same result. It logging the same error about magic bytes 
not matching. 

Any pointers to mistakes that I am making? 

Thanks,
~Abhi

Hi Nick, 

I added some debug statements and error statements to mod_deflate code and 
built the module. 
The error is coming from the following 

 /* We didn't get the magic bytes. */
        if (len != 10 ||
            deflate_hdr[0] != deflate_magic[0] ||
            deflate_hdr[1] != deflate_magic[1]) {
            ap_log_rerror(APLOG_MARK, APLOG_ERR, 0, r, "magic bytes don't 
match");        // ---> I Added this error message 
            return APR_EGENERAL;
        }

The client is using java.util's gzip to send a compressed message. Does that 
mean that the gzip created from java.util library is not compatible with the 
one that mod_deflate is using?? 




Thanks,
~Abhi

You should see quite a lot from mod_deflate if it's compressing
the output!

I can't say off the top of my head how much you'd see from it
doing nothing (as on your input), but at debug level I'd expect
it to tell you if it tries and fails to decompress something,
as opposed to (say) seeing content that's not labelled as
compressed and just getting out of the way.
