Content management [content] stanza doc-root = fully_qualified_path Root directory of the WebSEAL document tree. The administrator can either accept the default value of www/docs or specify an alternate location. When the administrator accepts the default value, the WebSEAL configuration appends the default value onto the WebSEAL installation directory. Thus the default fully_qualified_path is WebSEAL_installation_directory/www/docs When the administrator changes this value during configuration, the administrator must specify a fully qualified path. In this case, WebSEAL does not append the entry on to the WebSEAL installation directory. In this case, the doc-root entry is matches the administrator’s input. This stanza entry is required. Default value: WebSEAL_installation_directory/www/docs Example: doc-root = C:/Program Files/Tivoli/PDWeb/www/docs directory-index = filename Name of a directory index file. When a request is made for a directory located on the local WebSEAL server, WebSEAL looks for this file before attempting a directory listing. This stanza entry is required. Default value: index.html Example: directory-index = index.html delete-trash-dir = fully_qualified_path Path name to a directory in which files removed by the DELETE method are moved. Files are held there until an administrator removes them. This key does not apply to empty directories, which are always deleted. This key is inactive (commented out in the configuration file) by default. When the key is inactive, files removed by the DELETE method are immediately removed from the file system. This stanza entry is optional. There is no default value: Example: delete-trash-dir = /tmp/trashdir user-dir = filename Directory in users’ home directories that contain public HTML documents. This stanza entry is required. Default value: public_html Example: user-dir = public_html utf8-template-macros-enabled = {yes|no} Appendix A. WebSEAL configuration file reference 441
