This page is testing whether search indexing robots follow URL links for files ending in .ssi (usually generated by Server-Side Includes). For more tests, see the File Suffix Testing page and the List of Robot Tests.
The only link to this page is in the File Suffix Testing page, so if you search for the unique Keyword below and find this page, the search engine robot follows links and indexes text in .ssi files. If you do not find anything, the robot does not index these files.
