I have an almost working code to connect to a server and do a search. But there is some issue here with the code. This is what I do now with the following python script. I login to the site. Construct a url for the search result and access the search page and open it in a browser. But issue I am facing here is that I am getting a session expired page. But if I have a logged in page open(manually) in the browser, this constructed url is giving me the desired output. So my question here is that How can I keep the ‘logged in’ session in the script active and open the constructed url in a browser which yield me the desired output.

    You need to share the session (or session identifier, which is probably stored in a cookie) between Mechanize and your browser. This is not easy, and definitely not portable between browsers (if you want that).

    However, there appears to be support in Mechanize for the SQLite database format that Firefox uses since version 3:
    https://github.com/jjlee/mechanize/blob/master/mechanize/_firefox3cookiejar.py

    You may want to check the documentation for that.
