[android-developers] Re: HTTPS POST problem
Note that if a request goes through once and the identical request
doesn't show up on the server when issued a second time it's likely
because somewhere along the way the response is being served out of a
cache.

Re: [android-developers] Re: HTTPS POST problem
We start to use,
Post but the same problem still continue.
Some time we can catch the response, sometimes we couldnt connect server.
All parameters are true.

[android-developers] Re: HTTPS POST problem
You may have a problem with param encoding.
Also note that you should not have to specify ay https classes, if
done properly the client will switch to https as needed.
Unless you really need a GET it also might be better to use a POST.
I keep meaning to move my http client code into a library, but i
haven't yet so its not easy to send you some quick code, hoever if you
look thought the samples, you will find several implementations that
work well.
