Controlling cache sizes

If you use an infinite loop and the number of cached responses in a test increases exponentially, you can set a limit to cache for a user group in the schedule.

About this task

When the cache limit is reached, the least-recently accessed cached entry is released to accommodate a new entry. Also, when a test follows another test in the schedule, you can clear the cache before a test starts.


  1. To clear the cache before a test starts, from the Test Navigator, open a test.
  2. Click the HTTP Options tab and select the Clear page cache when the test starts check box.
  3. To set a limit to the number of cache entries, in the Test Navigator, navigate to a schedule and double-click it to open it.
  4. Click the user group for which you want set the cache limit.
  5. Click the Options tab and then click Edit Options.
  6. Select the Set cache size limit check box and, in the Maximum cache size field, type a numeric value.
    This value indicates the number of entries allowed for a user.
  7. Click OK and save the schedule.
