The webMathematica Interface
John Renze has implemented a convenient web interface that can easily be extended to include more search criteria. Pull-down menus specify which functions, constants, numbers, and operations should be included or not included in the search parameters. To avoid long pull-down menus, functions are grouped into Elementary Functions, Bessel and Airy Functions, and so on. Being able to freely add or remove search criteria is a nice feature typically found only in mail programs, not on web pages.
After clicking the Search button, a canonical form of the search request is sent to a server that runs webMathematica. The server starts a Mathematica session, the specified search is carried out, the results are analyzed, and a web page containing gifs of the resulting identities is assembled and returned.
