Subject [jira] Commented: (HTTPCORE-241) "Socket Exception: Bad file number" when passing chunked entity back to response
Date Wed, 24 Nov 2010 18:35:18 GMT

    [ https://issues.apache.org/jira/browse/HTTPCORE-241?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12935431#action_12935431

John B. Hansen commented on HTTPCORE-241:

Oleg, thanks again for your support.

I'm leaning towards porting and using the latest and greatest 4.1 (GA) in my
Android App and urging Google team to support it going forward.

I'm thinking that will insulate me from changes on their side if I cannot
persuade them to upgrade the HttpCore support in Android.

Thanks again!

>          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.
>            Reporter: John B. Hansen
> 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.
