session maintenance with two different HttpClient objects
Hi
I'm using HttpClient library for writing a specialized http client.
Let's say I have two instances of HttpClient object obj1 and obj2, which communicate with same application running in web server. This application provide two operations - "login" and "getDetails", which need session maintenance using cookies.
I am using obj1 and obj2 as follows -
1. Call "login" operation using obj1 and extract the cookie from the response.
2. Call "getDetails" operation using obj2 after setting cookie extracted in step 1.
But my "getDetails" fails saying that login is required. However, if I use obj1 in step 2, it works fine.
Basically, I've a special requirement to use *two different* instances of HttpClient to communicate with same web service (which needs session maintenance).
Am I missing something? Does session maintenace works only if all the operations are called using same HttpClient object?
Any help will be greatly appreciated.
thanks & regards,
Naresh Agarwal

Possibly there are more than one cookie involved.

HttpClient maintains the session state using an instance of a class
called HttpState. One can easily override the default HTTP state object
by specifying a different one as a parameter to HttpClient#executeMethod
call. In your particular case I do not think you have to maintain two
distinct instances of HttpClient. It may be sufficient to simply maintain
two HttpState instances and use the same HttpClient instance to execute
requests. The benefit of minimizing the number of HttpClient distances
involved is the potential performance improvement through the reuse of
persistent connections.

This is not the case.
Hope this helps
