Regular expression to remove jsessionid from the URL using java [closed]

Question

I need to remove the jsessionid from the given URL .The jessionid is not in the query part for example i have URL like

http://example.com/index.do;jsessionid=XXXXXXXXXXXXXXX?username=example

Answer 1

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:

• http://example.com/index.do;jsessionid=XXXXXXXXXXXXXXX
• http://example.com/index.do;jsessionid=XXXXXXXXXXXXXXX?username=example

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