Mungo currently defaults to serving all files as text/html. It should try to use any existing Apache (mod_mime) settings before finally falling back to text/html.
To reproduce, add the following to httpd.conf
<Files ~ (\.(asp|css|js|html|xml))>
PerlSetVar StatINC 1
If a doctype of:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
You can add the following to httpd.conf
<Files ~ (\.(css))>
PerlSetVar MungoContentType 'text/css'
<Files ~ (\.(js))>
<Files ~ (\.(xml))>
PerlSetVar MungoContentType 'text/xml'
but Mungo should respect (or at least try to obtain) those types already set in conf/mime.types.
If reading from conf/mime.types is too difficult/expensive, a single place (mungo.mime ?) to record all those associations would be appreciated.
