I'm trying to filter Apache output for a WebDAV client. My filter works as expected with plain HTTP, but when a WebDAV client posts an OPTIONS request, things die: WITH FILTER ON: 
OPTIONS /website/trunk/community/ HTTP/1.1
Host: svn.dubya-dev

Connection closed by foreign host.

This happens even if I program the filter to just pass buckets without doing anything to them. The only way it works is if I completely disable the filter in httpd.conf. Are there steps I need to take to make mod_perl i/o filters compatible with WebDAV? Thanks for any help.
