Info

You can configure the specific graphical icons used by WebSEAL for each file type listed in a generated index. The [content-index-icons] stanza of the WebSEAL configuration file contains a list of the document MIME types and the associated .gif files that are displayed: [content-index-icons] image/*= /icons/image2.gif video/* = /icons/movie.gif audio/* = /icons/sound2.gif text/html = /icons/generic.gif text/* = /icons/text.gif application/x-tar = /icons/tar.gif application/* = /icons/binary.gif You can configure this list to specify other icons for each MIME type. Icons can also be located remotely. For example: application/* = http://www.acme.com/icons/binary.gif You can also configure these additional icon values: v Icon used to represent sub-directories: [icons] diricon = /icons/folder2.gif v Icon used to represent the parent directory: [icons] backicon = /icons/back.gif v Icon used to represent unknown file types: [icons] unknownicon = /icons/unknown.gif Note: The supplied icons are in GIF format, but this format is not required. Windows: File naming for CGI programs Parameters contained in the [cgi-types] stanza of the WebSEAL configuration file allow you to specify the Windows file extension types that are recognized and executed as CGI programs. The UNIX operating system has no file name extension requirements. File extension types must be defined, however, for Windows operating systems. The [cgi-types] stanza lists all valid extension types and maps each extension (when necessary) to an appropriate CGI program. [cgi-types] = By default only those files with extensions matching those listed in the stanza will be executed as CGI programs. If a CGI program has an extension that is not contained in this list, the program will not be executed. Files with the .exe extensions are run as programs by Windows default and require no mapping. Note: Anytime you want to install a .exe file on Windows for download, however, you must rename the extension or install the file as part of an archive (such as .zip). You must supply the appropriate interpreter programs for extensions that represent interpreted script files. Examples of these types of extensions include: shell scripts (.sh and .ksh), Perl scripts (.pl), and Tcl scripts (.tcl) files. 76 IBM Tivoli Access Manager for e-business: WebSEAL Administration Guide
The following example illustrates a typical [cgi-types] stanza configuration: [cgi-types] bat = cmd cmd = cmd pl = perl sh = sh tcl = tclsh76 Executable UNIX files on the WebSEAL server host system WebSEAL supports the creation of local junctions. These junctions exist on the same host system as the WebSEAL server. When accessing a local junction on a UNIX system, WebSEAL interprets files as CGI scripts if the files are given the UNIX execute permission. For example, if an HTML page located on the local WebSEAL junction is given execute permission, WebSEAL interprets the file as an executable, and will not display it. To ensure that local files are displayed correctly, remove execute permission from all non-CGI files that are accessed through the local junction. Configuring Web document caching Clients can often experience extended network access time and file downloading time due to poor Web document retrieval performance. Poor performance can occur because the WebSEAL server is waiting for documents retrieved from junctioned back-end servers or even slow local storage. Web document caching gives you the flexibility of serving documents locally from WebSEAL rather than from a back-end server across a junction. The Web document caching feature allows you to store commonly accessed Web document types in the WebSEAL server’s memory. Clients can experience much faster response to follow-up requests for documents that have been cached in the WebSEAL server. Cached documents can include static text documents and graphic images. Dynamically generated documents, such as database query results, cannot be cached. Caching is performed on the basis of MIME type. When you configure WebSEAL for Web document caching, you identify the following three parameters: v Document MIME type v Type of storage medium v Size of storage medium You define Web document caching in the [content-cache] stanza of the WebSEAL configuration file. The following syntax applies: = : Parameter Description mime-type Represents any valid MIME type conveyed in an HTTP ″Content-Type:″ response header. This value may contain a asterisk ( * ). A value of */* represents a default object cache that will hold any object that does not correspond to an explicitly configured cache. Note that the asterisk here is a wildcard only for a MIME-type directory, and its contents. This is not a wildcard for regular expression matching. Chapter 3. WebSEAL server administration 77
