[android-developers] Re: HttpsURLConnection's getResponseCode() returns -1
Hi,
I sometimes had similar kind of problems, where one request received
the correct responseCode but the second request to the same URL failed
with request code -1. After setting http.keepAlive system property to
false, everything started to function properly. So maybe you could try
adding this line System.setProperty(http.keepAlive, false); to
your code. Maybe it'll help.

m_data is null, so it is performing a GET and no data is written.
Thanks

[android-developers] Re: HttpsURLConnection's getResponseCode() returns -1
Thanks for the tip, that does indeed fix the problem. Can you tell me
what the ramifications of setting the keepAlive to false are?
Thanks.
