Re: [naviserver-devel] nsphp and other broken things

Ok, while preparing test case i was able to pinpoint the location of the 
problem.
I use PmWiki and it uses If-modified-Since header to return 304 
responses. In new code send_headers was no-op but actually i have to 
call Ns_ConnWriteData with 0 length to flush headers.

Now it works, it was module problem.
