To configure your server to compress content on demand

1. From the Class Manager, click the Content Management tab.

2. Click Compress Content on Demand.

3. Enter the following information:

   • Editing. Select the resource from where compressed content will be served dynamically on demand from the drop-down list. If you choose a directory, the server will serve compressed content only when the server receives a URL for that directory or any file in that directory.

     Click the Browse button to browse the primary document directory, or click the Wildcard button to specify a wildcard pattern. For information on using wildcard patterns, see Wildcards Used in the Resource Picker.

     • Activate Compress Content on Demand? Choose whether the server should serve precompressed content for the selected resource.

     • Vary Header. Specify whether to insert a Vary: Accept-encoding header. Select either yes or no.

       If set to yes, then a Vary: Accept-encoding header is always inserted when a compressed version of a file is selected.

       If set to no, then a Vary: Accept-encoding header is never inserted.

       By default, the value is set to yes.

     • Fragment Size. Specifies the memory fragment size in bytes to be used by the compression library (zlib) to control how much to compress at a time. The default value is 8096.

     • Compression Level. Specifies the level of compression. Choose a value between 1 and 9. The value 1 yields the best speed; the value 9 the best compression. The default value is 6, a compromise between speed and compression.

4. Click OK.
