What is the use of <c:param > tag in JSP?
The <c:param> tag allows proper URL request parameter to be specified with URL and also does the necessary URL encoding required.
Within a <c:param> tag, the name attribute indicates the parameter name, and the value attribute indicates the parameter value −

The <c:param> tag has the following attributes −
| Attribute | Description | Required | Default |

If you need to pass parameters to a <c:import> tag, use the <c:url> tag to create the URL first as shown below −
<c:url value = "/index.jsp" var = "myURL">
<c:param name = "trackingId" value = "1234"/>
<c:param name = "reportType" value = "summary"/>

<c:import url = "${myURL}"/>The above request will pass the URL as below - Try it yourself.
