URL Trace Generation Feature

The new URL Trace Creation feature is intended to make it possible to run tests, for comparison purposes, in eValid that mimic some types of less-sophisticated browser traffic generators such as those based in HTTP sequences.

In operation the new URL Trace Creation feature generates a derived script at playback time that contains the specific sequence of GetURL commands to account for every URL that the eValid browser downloaded during the script playback. The resulting derived eValid script can be used in different ways: for server load timing experiments, to create non-browser server activity, and for performance comparison purposes.

Total URL-only playback time typically exceeds that of eValid browser based playback because the browser activity is multi-threaded, whereas the sequence of GetURL commands executes serially (single thread, no parallelism).
