In Netscape 1.0-4.x, when data is sent via POST, it is sent as a name/value pair (exactly like it is done with normal forms.) The data is sent as: The ISINDEX value is what is entered by the user, and the variable name it is assigned to is "isindex." If the GET method is used, the value is the only data that is sent.

Clicking on the link will generate the ISINDEX test case. Click on the link, type some text in the isindex box and hit the enter key.
