[MKDoc-modules] [BUG] MKDoc::Apache_Cache only serves pages already cached

[Bruno Postle]

1. URLs that are not cached by policy are ok.

2. URLs that are cached by policy fail when fetched initially:

       $lynx -source -dump http://www.example.com/sq/welfare/
 
       HTTP request sent; waiting for response.
       Alert!: Unexpected network read error; connection aborted.

   This appears in the server-log:

       GET /sq/welfare/ HTTP/1.0" 200 - "-" 

   However the cache file is created ok.

3. When fetching the URL a second and third time, everything is ok,
   this is written to the log:

       GET /sq/welfare/ HTTP/1.0" 200 16894 "-"

This is probably related to the other bug I found, non-existant URLs
fail repeatedly in the same way, regardless of whether they match
the cache-policy:

    $lynx -source -dump http://www.example.com/sq/wsdfdsfds/
        
    HTTP request sent; waiting for response.
    Alert!: Unexpected network read error; connection aborted.

Though I get a correct 404 error (with no length) in the log:

    GET /sq/welfare/sdfdsf HTTP/1.0" 404 - "-"
