I seem to get extremely high numbers of HttpRecoverableExceptions when
accessing a web site via HTTPS. No such problem is seen with HTTP.
Generally, by bumping up the number of repeated attempts (from 3 to 25) it
will almost always succeed eventually, but this seems like a real kludge and
I'd like to understand and resolve the root cause.
I see slightly different stack traces depending on whether the client is
executing on a Windows or a UNIX (HP-UX) box:

On Windows 2000, the SocketException is 'recv failed', rather than 'broken
pipe' when trying to read back the response.
I can find several references to these errors on the Java Forums at Sun, and
they do seem to be associated to the use of SSL - but there is no solution
posted that I could find, and most of the attempted workarounds use the
standard Sun classes (URLConnection). Has anyone run into this using
HttpClient, and is there a workaround or solution (other than
retry-until-success?)
Thanks,
Mike
