How to Search for Values that Need Correlation

Search by Comparing Scripts

  1. Record a script and save it.

  2. Create a new script and record the identical operations. Save the script.

  3. Select Tools > Compare with Vuser to compare the scripts. For more details, see How to Compare Scripts Side-by-Side.

  4. Differences in the script are highlighted. Review the differences to determine which ones may require correlation.

  5. Note: WDiff is the default utility, but you can specify a custom comparison tool. For more information, see How to Compare Scripts Side-by-Side.

Replay Log Search

  1. Scan the script in script view for strings that may need correlation such as hash strings, random strings, session ID's, and so on.

  2. Search the generation log for the first time that the string appears (this is the response from the server).

  3. Search the extended replay log for the same response. Check to see if this response contains a different string within the same boundaries as the original suspected string. If yes, this string requires correlation.
