Severity: 3-Major
URI::path, URI::basename, etc., return the wrong strings, e.g., URI::path can return a subset of what it should return.
iRules fail to work as expected for these types of URIs. This occurs because the combination of the period and semi-colon in 'Some.thing;param' confuses the BIG-IP system parser, causing incorrect results to be returned.
This happens for URIs like these: /alpha/beta/Sample.text;param/trailer/ /alpha/beta/Sample.text;param/file.txt
If this is happening for known URIs, then it should be possible to process those URIs in a special way within iRules to do things like temporarily replacing interior periods with another character, like a plus sign.
