This isnt easy to do. If your application supports URL rewriting(sending sessionids in URL) then you may be able to do this or else you will have to interact with cookie manager.
Something like below Thread Group (even number if threads for your case, Odd numbered threads will execute request1 and even numbered threads will execute request2 , so you are simulating 10 browsers then 20 threads - assuming 2 requests run in parallel) +If odd numbered thread then ++http request create session +++Extract session id +++BSH listener setup session id in JMeter Properties using say thread number as the key and session id as value (Properties are shared across threads) +Simple Controller ++Test Action +++Synchronizing timer (wait for everyone to have setup their sessions) +If odd numbered thread ++Http Request1 +++BSH which adds session id to request , read from corresponding property using thread numbers in JMeter Properties +If even numbered thread ++Http Request2 +++BSH which adds session id to request , read from corresponding property using thread numbers in JMeter Properties +Simple Controller ++Test Action +++Synchronizing timer (wait for everyone to have setup their sessions) +If odd numbered thread then ++http request end session Please note I havent tried this so you may run into some issues. You could also have variations where you split this into thread groups where the creating of sessions is a separate thread group (which writes all ids to file ) and then the next thread group picks this up .. regards deepak On Wed, Jun 9, 2010 at 4:35 AM, Oleg Olenin <[email protected]>wrote: > Hi, > > I need to simulate in test the behavior of N browsers, every of them sends > several concurrent (parallel) HTTP requests to HTTP server. > Every request from the same browser is processed in scope of the same HTTP > session, so all these parallel requests have the same cookie with session > id.
