What is the use of <c:url > tag in JSP?

JSPJava 8Object Oriented ProgrammingProgramming

The <c:url> tag formats a URL into a string and stores it into a variable. This tag automatically performs URL rewriting when necessary. The var attribute specifies the variable that will contain the formatted URL.

The JSTL url tag is just an alternative method of writing the call to the response.encodeURL() method. The only real advantage the url tag provides is proper URL encoding, including any parameters specified by children param tag.

The <c:url> tag has the following attributes −
