[Catalyst] If-Modified-Since Plugin::Static Engine::Apache

[Andrew Bramble]

Hello, 

Has anyone else experienced problems with  $c->serve_static_file and Apache2/ 
mod_perl ? 

I have discovered that when running under modperl2 the initial request 
succeeds but a subsequent request for the same file (with header specifying 
'Is-Modified-Since' ) generates 500 internal error from apache in situations 
where Plugin::Static has set response status to 304. Nothing enlightening 
appears in the debug output, This does not occur when running with the 
catalyst http server. 

First observed this behavior on SuSE9.3 Professional , re-tested on 
opensuse10.0 (see versions below)

Have attached a tiny application that reproduces the problem. a request 
for /plugin/document.txt will serve up root/document.txt , a subsequent 
refresh of that page returns 500 error from apache. Also attached a 
conversation with apache via telnet.

$Catalyst::VERSION = 5.6902

apache2-prefork-2.0.54-10
apache2-mod_perl-2.0.1-4
perl-5.8.7-5.3
