What is the use of param tag in setProperty, include , forward commands?

Maxim Senin

In include and forward, params will be appended to query string, i.e.

newQueryString = requestURI+"?paramName1=paramValue1&paramName2=parmValue2"

In setProperty every param name corresponds to property name and every parameter value corresponds to property value, so that

<param name="user" value="Administrator" >
will set property user to value "Administrator"
