I'm trying to extract jsessionid from a sampler's response and reuse it for a third sampler. The sampler in between these two is an independent HTTP request which must not utilize any jsessionids.

I'm able to do this manually using a "Regular Expression Extractor" for the first sampler and requesting for jsessionid=${foobar} in the third sampler:

enter image description here

However, I'd like to accomplish this using the components specifically engineered for this purpose, like "Pre Processor → HTTP URL Re-writing Modifier" and etc.

How can we do URL rewriting for non-subsequent requests?

• Adding "HTTP URL Re-writing Modifier" to the third sampler doesn't work, because it will attempt to parse the response from the second sampler instead of the first one.

• Adding "HTTP URL Re-writing Modifier" to the second sampler doesn't work too, because while it is able to extract the jsessionid successfully, it uses that jsessionid for the second sampler instead of the third one.

  • Can you provide a screenshot of your problem so that we can see the order and arrangement of your samplers and assertions?

JSESSIONID is usually a cookie so you can use JMeter's HTTP Cookie Manager to refer its value.

  1. Add CookieManager.save.cookies=true line to user.properties file (it resides under /bin folder of your JMeter installation)
  2. Add HTTP Cookie Manager to your Test Plan
  3. Restart JMeter
  4. Refer "jsessionid" value as ${COOKIE_JSESSIONID} where required

    Hi, yes the usual implementation for sessions is using cookies, but in this case it's using URL rewriting, not cookies. The server does not send Set-Cookie at all and the sessions work even if the browser has cookies disabled. As such, while step 4 works on the sever when it uses cookies, it instead uses the literal string ${COOKIE_JSESSIONID} (because there are no matching cookies returned) when the server uses HTTP rewriting.

  • That sounds very unusual, and somewhat insecure for a site to implement sessions that way.

    @djangofan, It's not unusual at all, and that's the only way to do sessions without cookies. It's the same as PHPSESSID with session.use_cookies = 0.
