Name

<c:url>

Synopsis

The <c:url> action applies the appropriate encoding and conversion rules for a relative or absolute URL. Specifically, it handles three types of rules: URL encoding of parameters specified by nested <c:param> actions (converting special characters to hexadecimal codes); converting a context-relative path into a server-relative path; and adding a session ID path parameter for a context- or page-relative path (“URL rewriting”), if needed to enable session tracking. The result is either saved in a scoped variable or added to the current response buffer (JspWriter).

Syntax 1: Without a body

<c:url value="url" [context="externalContextPath"]
  [var="var"] scope="page|request|session|application"]] />

Syntax 2: With a body

<c:url value="url" [context="externalContextPath"]
  [var="var"] scope="page|request|session|application"]]>
  <c:param> actions
</c:url>
