[PATCH] StreamGenerator

           Summary: [PATCH] StreamGenerator
           Product: Cocoon 2
           Version: Current CVS 2.1
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: sitemap components
        AssignedTo: dev@cocoon.apache.org
        ReportedBy: gcasper@s-und-n.de


This patch is a companion to the WebDAV sample.
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=21878

If StreamGenerator doesn't find a HTTP header Content-Type it throws an 
exception. Since some WebDAV client don't set the Content-Type header (as Win2k 
Explorer) it is not possible to store new content into the davmap with these 
clients.

This patch allows the StreamGenerator to specify a default content type if the
HTTP header is missing.

  <map:match pattern="PUT/**/*.xml">
    <map:generate type="stream">
      <map:parameter name="contentType" value="text/xml"/>
    </map:generate>
    <map:transform src="styles/stream2write.xsl">
      <map:parameter name="file" value="{global:staging}{1}/{2}.xml"/>
    </map:transform>
    <map:transform type="write-source"/>
    <map:serialize/>
  </map:match>

It still throws an exception if there is a Content-Type header but its value
is not xml.

It feels somewhat hacky, but I don't know a better solution.

Additionally maybe org.apache.cocoon.util.PostInputStream should be renamed to
HTTPRequestInputStream. It's currently used only by StreamGenerator and
HTMLGenerator.
