Very Challenging HTTPConnection Problem

[MananW]

Hi All

I am using HTTPCOnnection in my MIDlet.
I do it with the help of Connector.open(URL)
After this I read data from connection through InputStream.

But The problem I am facing is once i read data from this connection it goes fine but when I read it again it gives problem.

Does anybody know how to resolve this.

Thanks and Regards,
Manan

hi,

have you:
- started separate thread (non-blocking):
- closed connection
- closed input stream
so e.g. your run() method ceased?
here is an example of using http connection to load/parser rss feed:

Ya I have done all these things.
But I think the problem is my application is using cache due to which I am getting problem

Hi,

One point:
- Emulator or real phone?

A common mistake, is to not close the http connection:
httpconnection.setRequestProperty("Connection", "close");

Also to be sure to not cache data:
httpconnection.setRequestProperty("Cache-Control", "no-cache");

I sometime use this trick to force new request:
req += "&rnd="+System.currentTimeMillis();
httpconnection = (HttpConnection)Connector.open(req);


Best,

Mik

What do you mean by "read it[the data] again"?

Are you trying to reuse the connection? Are you trying to reset the stream and read it from the beginning? Are you reading part of the data, then doing something else, then reading the rest? Are you reconnecting to the same URL using a new connection?

And what problem does it give exactly?
