Description

I have a cgi, which output a small image:

Content-type: image/png\r\n\r\n
(The image itself)

It works well without mod_deflate.
But after applying the patch "lighttpd-1.4.13.mod_deflate.jz.patch",
a browser always wait for more output, and for most cases the image
can not be displayed.

But for fastcgis, it seems ok.

I have this problem with regular cgis. This includes awstats and mailman. The log contents for a request to awstats.pl:
