To Compress Content on Demand

1. From the virtual server page, click the Content Handling tab.

2. Click the General sub tab. Go to Compression > Compress Content on Demand.

3. Select from the following options:

   • On—Demand Compression — Enables/Disables on-demand compression for the selected resource.

   • Insert Vary Header — Specifies whether to insert a Vary: Accept-encoding header.

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

     If not selected, then a Vary: Accept-encoding header is never inserted.

   • 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 Save.
