I forgot that vital info, I had "follow redirects" on and not Redirect automaticlly. For my need this should right - follow redirects. The strange this is when running with the browser the same session and recording with ethereal I do not see any 302 for the server.

Trying to use jmeter to do load simulation and response time measuring. The problem I have was discovered when I need to pickup returned data from the server response and use it into the next request. Being new to jmeter I did not understand the inbuilt recording mechanism in jmeter. Instead I used ethereal to record my session. The request in question is POST with Name Value pairs. So I created a Http Request sampler (also tried the Http Request HttpClient sampler) with my recorded request and then created a Post Processor regular expression extractor. The problem was I was not getting any hits on the regular expression that I expected from the recording done in ethereal. After testing the limits of my regular expression knowledge, I save I could get hits on other stuff changing the regular expression. To debug what was going on I added both "functional test mode" on the testplan and for each http request a "Save response to file" post processor and a "simple data writer" listener. What I discovered was that none of the stuff I was looking to match on was in the result. It looked that I was missing a lot of expected response. In the result from the "Save response file" listener I had strings like "invoked "break" outside of a loop" in the html files stored. Running my script and using ethereal recording I could see I got a "HTTP/1.1 302 Found" reply sending my POST requests instead of the expected. Maybe my HTTP knowledge is to limited but a 302, according to the spec talk about "The requested resource resides temporarily under a different URI" and I real do not know what I should do or what it would mean in this context.
302 is a redirect. Browsers follow redirects automatically - not sure if any of them allow this to be switched off.
However, unless you set the HTTP Sampler to *follow* redirects, JMeter considers it has finished the sample as soon as it receives the initial response, i.e. the redirect.
JMeter gives you the options: * redirect automatically - i.e. the http connection does the redirect, and JMeter never sees it. * follow redirects - i.e. JMeter uses the information from the 302 to load the new page. Both the pages willl appear as samples. * or neither, of course.
This is described in the user manual, see: http://jakarta.apache.org/jmeter/usermanual/component_reference.html#HTTP_Request
