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>
