svn commit: r563154 - /httpd/httpd/trunk/modules/filters/mod_deflate.c

[ni...@apache.org]

Author: niq
Date: Mon Aug  6 07:37:42 2007
New Revision: 563154

URL: http://svn.apache.org/viewvc?view=rev&rev=563154
Log:
Don't try to compress/decompress where there's a Content-Range.
According to RFC2616, the range would have to apply *after*
applying content-encoding, so anything that's been set before
running the deflate filter is going to be broken.
