Writing an HTTP 1.1 Protocol Resource Policy

Protocol resource policies enable or disable HTTP 1.1 protocol support between the system and backend servers. The system supports chunked Transfer-Encoding, gzip and deflate Content-Encoding, connection persistence, and caching headers such as If-Modified-Since, If-None-Match, If-Unmodified-Since and If-Match. The system supports range requests with partial content when you select the Don't rewrite content: Do not redirect to target web server selective rewrite option.

For a detailed description of the HTTP 1.1 protocol, refer to the Hyptertext Transfer Protocol -- HTTP 1.1 specification from the World Wide Web Consortium.

The system only communicates with network servers using HTTP 1.1 if the client also communicates using HTTP 1.1. If the client uses HTTP 1.0, the system communicates with backend servers using HTTP 1.0, regardless of whether or not HTTP 1.1 is enabled.

If you want to use HTTP 1.1 for a specific resource, enable HTTP 1.1 for that policy and ensure that the new policy appears above the default in the list of configured policies. You should add the HTTP 1.1 policy to the top of the policy list because the policy evaluation engine evaluates policies from top to bottom, stopping when it encounters a match.

The system comes with a default policy that disables HTTP 1.1 for all resources. If you want to use HTTP 1.1 for all resources, either redefine the "*:*/*" policy or create a new policy enabling HTTP 1.1 and move it to the top of your policy list. If you delete this default policy (and any other policies that disable HTTP 1.1), the system uses HTTP 1.0 for all resources

To write an HTTP 1.1 protocol resource policy:

In the admin console, choose Users > Resource Policies > Web.

If your administrator view is not already configured to show protocol policies, make the following modifications:

Click the Customize button in the upper right corner of the page.

Select the Protocol check box.

Click OK.

Select the Protocol tab.

On the Web Protocol Policies page, click New Policy.

Enter a name to label this policy (required) and a description of the policy (optional).

In the Resources section, specify the URLs to which this policy applies.

In the Roles section, specify:

Policy applies to ALL roles - To apply this policy to all users.

Policy applies to SELECTED roles - To apply this policy only to users who are mapped to roles in the Selected roles list. Make sure to add roles to this list from the Available roles list.

Policy applies to all roles OTHER THAN those selected below - To apply this policy to all users except for those who map to the roles in the Selected roles list. Make sure to add roles to this list from the Available roles list.

In the Action section, specify:

Disable HTTP 1.1 - Automatically communicate with backend servers via the HTTP 1.0 protocol.

Enable HTTP 1.1 - Automatically communicate with backend servers using the HTTP 1.1 protocol as long as the client also communicates using the HTTP 1.1 protocol.

Use Detailed Rules - Select this option to specify one or more detailed rules for this policy.

Click Save Changes.
