考试ple 12: Configure rewrite to change the host name and URL in client request on Citrix ADC appliance
Rewrite feature on a Citrix ADC appliance is used to convert the URL available in the client request to another URL that the back end server can understand. You can achieve the following benefits by using the rewrite feature:
Enhances the security by hiding the actual URL to the resource, which is requested by the client.
Prevents the unauthorized user access from gaining access to the network resources.
考虑一个例子,你当前的组织n is acquired by another organization. It becomes a difficult job for admins to inform about the new web address to every user of the acquired organization. In this scenario, using rewrite feature becomes convenient to change the host name and URL in the client requests for the website of the acquired organization. You can use rewrite to change the URLs in the client request temporarily when the website is under maintenance.
The following section describes the procedure to change the host name and URL in a client request using rewrite feature.
Consider an example where the user enters ahttp://www.example.com
URL in the web browser. The website administrator wants the Citrix ADC appliance to convert the preceding URL in the client request ashttp://myexample.example.net.in/resource/inventory/s?t=112
.
In the preceding example, the website administrator wants the Citrix ADC appliance to replace the “example.com” domain name with “myexample.example.net.in” and the URL with “resource/inventory/s?t=112”.
Log on to the Citrix ADC appliance using SSH.
Add rewrite actions.
add rewrite action rewrite_doman_url_repalce_act replace HTTP.REQ.URL "\"http://myexample.example.net.in/resource/inventory/s?t=112\""
添加重写重写政策行动。
add rewrite policy rewrite_domain_url_pol HTTP.REQ.HOSTNAME.EQ("www.example.com") rewrite_doman_url_repalce_act
Bind the rewrite policies to a virtual server.
bind lb vserver rewrite_LB -policyName rewrite_domain_url_pol -priority 100 -gotoPriorityExpression END -type REQUEST
