Use the
mirrormethod. This works fine forGETrequests, see themethodattribute of theformelement which you are submitting. Just take note of the URI where you arrived, use it to repeatedly callmirror. Then there is no need to fill and submit the form anymore.In the case of
POST, you are not able to leverage any assistance from the HTTProtocol (conditional requests, ETags and other cacheability features). You have to manually write out fetched results to files, then compare them.
