>             Project: HttpComponents HttpCore
>          Issue Type: Bug
>          Components: HttpCore
>         Environment: Android Froyo 2.2 (FRF50)
> Running as Root on a Nexus One
> I think Android Froyo is running HttpCore 4.0 but not sure. I tried to dump VersionInfo
on several packages but didn't get any info returned.

> I'm a new user with HttpCore and didn't know where else to turn for support.. And, this
problem may be my fault...
> Just looking for some suggestions...
> I'm doing a ProxyServer by using a variation of ElementalHttpServer  to send a request
to proxy code.
> The proxy code then makes an actual client request to the target site. The proxy request
gets a response
> back and sets the statusline, headers, and entity back in the original response in the
 handler  (which sends
>  it back to the Browser).
> For simple HTML sites, this works fine. But, on chunked sites (transfer-encoding=chunked)
e.g. www.google.com 
> I'm getting a "Socket Exception: Bad File Number" following the first response back to
the browser i.e.

> BTW: I have no reason to suspect bugs in the Chunk handling. I'm just not seeing this
on the few non-chunked sites I've tested.
> Any ideas what could be wrong or how to debug? Any advice appreciated....Thanks!
> PS, if anyone can clarify the version of HttpComponents on Android 2.2 also, that would
be great. Thx.
