Try this:

url = url.replaceAll(";jsessionid=[^?]*", "");

This will work whether or not your url has any parameters, eg, it will work for both of these:

It employs a regex "look ahead" to capture up to (but not including) either a ? or end of input.

Maybe a simpler version like ";jsessionid=[0-9A-Za-z]*" should be enough ? – morellet.d Nov 09 '16 at 15:13
@morellet.d actually it can even simpler: `url = url.replaceAll(";jsessionid=[^?]*", "");` – Bohemian Nov 09 '16 at 15:18
