webMathematica User Guide 297Mathematica Web FunctionswebMathematica contains a large number of Mathematica commands that can be used insidethe webMathematica tags that provide useful functionality for creating web material with Mathematica.These are useful in various ways such as processing request parameters that are theinput from a web user, formatting results, and using web features such as uploading files andHTTP sessions.Typically, these commands are used inside of an evaluate tag; more information on these tagsis found in the webMathematica tags section. An example, which calculates an integral and usesthe function MSPFormat to format the result into TraditionalForm, is shown below.MSPFormat[ Integrate[ expr, {var, 0, Infinity}], TraditionalForm]The different functions are shown in the following sections.Processing InputHTTP input variables are a key way to control the operation of a dynamic website.
