Currently I am evaluating HDIV. Its a great tool to implement various levels of security. But currently I need to check its performance. ie after implementation of HDIV, what is the load time of my subsequent pages with _HDIV_STATE appended to the request.

But as this value is dynamically generated and is session/user/token specific, I am not able to configure the flow of events in JMeter. ie how do i get the generated value of HDIV_STATE which is dynamically generated and appended to my next link. Help on this will be highly appreciated.

You can also let me know in case if some other tool i can use to get this done. In short I need time ie if 100 users right now are accessing my website, what would the load times of the page with HDIV and without HDIV.

It is classic "correlation" challenge example. Basically you need the following:

  1. Execute 1st request
  2. Extract _HDIV_STATE from the response and save it to JMeter Variable
  3. Append the JMeter Variable to 2nd request
  4. Repeat steps 1-4 for any subsequent request

Depending on response nature you can use the following Post Processor test elements:

  • Regular Expression Extractor - evaluate a Perl5-style regular expression against the response and store match value into a variable - should cover 90% of all needs
  • CSS/JQuery Extractor - designed to extract information from HTML pages using CSS selectors and/or JQuery syntax
  • XPath Extractor - the same for XML and XHTML responses

See the following guides for step-by-step explanation on how to use above post processors:
