AW: How to capture HTTP response with the status 500?

I just had a look at the source code.
There is a special handling for HTTP-ResponseCodes for 
- MOVED --> follow redirect if specified
  -- 301: Moved Permanently
  -- 302: Temporary Redirect
  -- 303: See Other
  -- 307: Temporary Redirect
- HTTP_NOT_MODIFIED (304 Not Modified) --> dont download if use timestamp
- HTTP_UNAUTHORIZED (401: Unauthorized) --> maybe throw BuildException, dont download

Otherwise the return of the url.openConnection().getInputStream() is copied to local file.

So a response for a 500-error should be captured to file.
_But_ that file is deleted if an error (non-success, e.g. catched IOException) occured.
(org.apache.tools.ant.taskdefs.Get:887).

For a workaround you could
- get the <get> source code
- modify the deletion logic
- compile that code
- include your modified code via <taskdef name="get2" classname="..." classpath="..."/>
- try it out
(- provide a patch ;)


Maybe we could also tune that task.
- support of HTTP 308 Permanent Redirect
- store the HTTP-returncode in a map (URL-RC) for access via property ${get-rc.http://ant.apache.org}==200
- parallel downloads?
- different "delete" logic as specified via new attribute
  -- delete (old behaviour)
  -- move to different folder
  -- move to different name/folder (e.g. get-error/http-ant.apache.org--207_MULTI_STATUS)
