server-policy http-content-routing-policy

server-policy http-content-routing-policy

Use this command to configure HTTP header-based routing.

Instead of dynamically routing requests to a server pool simply based upon load or connection distribution at the TCP/IP layers, as basic load balancing does, you can forward them based on headers in the HTTP layer.

HTTP header-based routes define how FortiWeb routes requests to server pools. They are based on one or more of the following HTTP header elements:

  • Host
  • URL
  • Parameter
  • Referer
  • Cookie
  • Header
  • Source IP
  • X.509 certificate
  • Geo IP

This type of routing can be useful if, for example, a specific web server or group of servers on the back end support specific web applications, functions, or host names. That is, your web servers or server pools are not identical, but specialized. For example:

  • 192.0.2.1—Hosts the website and blog
  • 192.0.2.2 and 192.0.2.3—Host movie clips and multimedia
  • 192.0.2.4 and 192.0.2.5—Host the shopping cart

If you have configured request rewriting, configure HTTP content-based routing using the original request URL and/or Host: name, as it appears before FortiWeb has rewritten it. For details about rewriting, see waf url-rewrite url-rewrite-policy.

To apply your HTTP-based routes, select them when you configure the server policy. For details, see server-policy policy.

To use this command, your administrator account’s access control profile must have either w or rw permission to the traroutegrp area. For details, see Permissions.

Enter a HTTP content routing policy sequence number.

No default.

match-object {http-host | http-request | url-parameter | http-referer | http-cookie | http-header | source-ip | x509-certificate-Subject | x509-certificate-Extension | https-sni | geo-ip}

Enter the type of value to match. Values can be a literal value that appears in the object or a regular expression.

The value of match-object {http-host | http-request | url-parameter | http-referer | http-cookie | http-header | source-ip | x509-certificate-Subject | x509-certificate-Extension | https-sni | geo-ip} determines which content types you can specify.

    dname1.abc.com
    dname1.dname2.abc.com

    However, the same Match Simple String value does not match the following hostnames:
