You must be familiar with the information in the iTP Secure WebServer System
Administrator’s Guide to understand this section of the manual.
Passing Request Information to a Servlet
You can pass request information to a servlet in any of the following ways:

Query strings appended to URLs: The servlet receives this data through the
QUERY_STRING environment variable.

Extra path information appended to URLs: The servlet receives the path
information through the PATH_INFO and PATH_TRANSLATED environment
variables.

HTML forms: A servlet receives data from HTML forms in an input stream.
A servlet accesses the environment variable and the input stream through an object,
as described in Using the Servlet API on page 4-4.
