In addition to Bug 49083 does Wicket not only produce collapsing URLs like "app/path/../path2/" but also relative paths like "app/wicket/./login?0" in redirected URLs. Current Browsers fix URLs with "/./" by removing "/./" but not JMeter. In this Bug the problem with relative paths shall be fixed by replacing "/./" by "/" in the URLs getting by redirection.
Created attachment 36063 [details] Patch Patch for this Bug
If you look at ConversionUtils#removeSlashDotDot, you will see, that it does a lot more than simply removing '/..' from the complete URL. Maybe it would be a good idea to factor out the common logic of /.. and /. into a new method and delegate the old one and the new one (you would have to create, too) to it. And by the way. String#replaceAll takes a regex as first command and '.' has a special meaning in regex, so it is probably a good idea to add test cases for the change :) It should be easier, if you take the route via ConversionUtils.
