Excessive hits to missing URLs uses up all ports on Windows

      windows xp sp3, running Ivy repository through http for remote resolving


      Modified description to be clearer:
      Ivy is extremely aggressive towards repositories . This can result in
      failures to resolve, even against a healthy repository and with no network latency.

      The symptom:

      [ivy:resolve] 01-07-2008 13:16:24
      org.apache.commons.httpclient.HttpMethodDirector executeWithRetry
      [ivy:resolve] INFO: I/O exception (java.net.BindException) caught when
      processing request: Address already in use: connect.

      This is especially a problem with large repositories (lots of revisions) and resolving against latest.integration as this will fetch ivy.xml md5 and sha1 files for every revision.

      As I've included in a comment, the problem appears to be Ivy's attempts to list URLs that don't actually exist. Ivy builds up URLs using the repository location and appending organizations and module names. We have ivy chains that contain 5 links or more. So for each successful attempt to list an URL, there are several attempts to list non-existent URLs. This is wasteful in terms of time, and can lead to using up all of the available Windows ports on the client machine.
