Content compression v [compress-mime-types] v [compress-user-agents] [compress-mime-types] stanza mime_type = minimum_doc_size:[compression_level] Enables or disables HTTP compression based on the mime-type of the response and the size of the returned document. The mime_type can contain a wild card pattern such as an asterisk ( * ) for the sub-type, or it can be ″*/*″ to match all mime-types. The minimum_doc_size is an integer than can be positive, negative or zero. A size of -1 means do not compress this mime-type. A size of 0 means to compress the document regardless of its size. A size greater than 0 means to compress document only when its initial size is greater than or equal to minimum_doc_size. The compression_level is an integer value between 1 and 9. The larger number results in a higher amount of compression. When compression-level is not specified, a default level of 1 is used. This stanza entry is optional. There is one default entry: */* = -1 Examples: image/* = -1 text/html = 1000 [compress-user-agents] stanza pattern = {yes|no} Enables or disables HTTP compression based on the user-agent header sent by clients. This entry is used to disable compression for clients which send an ″accept-encoding: gzip″ HTTP header but don’t actually handle gzip content-encodings properly. An example of a user agent is a browser, such as Microsoft Internet Explorer 6.0 This stanza entry is optional. There is no default entry: Example: *MSIE 6.0* = yes 452 IBM Tivoli Access Manager for e-business: WebSEAL Administration Guide
Content MIME types [content-mime-types] stanza extension = MIME_type This stanza defines the MIME type for specific document extensions. The stanza contains a list of extension = MIME_type pairs. Many common MIME types are defined by default. Administrators can add additional entries. Both extensions and MIME_types must be declared using the ASCII character set. The entry of invalid MIME types does not affect WebSEAL, but may cause difficulty for client browsers. v extension The file name extension of documents of this MIME type v MIME_type The corresponding MIME type There following MIME types are defined by default: html = text/html htm = text/html gif = image/gif jpeg = image/jpeg ps = application/postscript shtml = text/x-server-parsed-html jpg = image/jpeg jpe = image/jpeg mpeg = video/mpeg mpe = video/mpeg mpg = video/mpeg bin = application/octet-stream exe = application/octet-stream Z = application/octet-stream EXE = application/octet-stream dll = application/octet-stream DLL = application/octet-stream ivsrv = application/octet-stream pdf = application/pdf au = audio/basic snd = audio/basic aiff = audio/x-aiff aifc = audio/x-aiff aif = audio/x-aiff wav = audio/x-wav ai = application/postscript eps = application/postscript rtf = application/rtf zip = application/zip ief = image/ief tiff = image/tiff tif = image/tiff ras = image/x-cmu-raster pnm = image/x-portable-anymap pbm = image/x-portable-bitmap pgm = image/x-portable-graymap ppm = image/x-portable-pixmap rgb = image/x-rgb xbm = image/x-xbitmap xpm = image/x-xpixmap xwd = image/x-xwindowdump txt = text/plain rtx = text/richtext tsv = text/tab-separated-values etx = text/x-setext qt = video/quicktime mov = video/quicktime avi = video/x-msvideo movie = video/x-sgi-movie js = application/x-javascript ls = application/x-javascript mocha = application/x-javascript wrl = x-world/x-vrml dir = application/x-director dxr = application/x-director dcr = application/x-director crt = application/x-x509-ca-cert tar = application/x-tar deftype = MIME_type Default type to assign to pages that don’t match any of the extension = MIME_type entries defined in this stanza.
