Additionally, when an organization acquires another organization, it is difficult to inform every user of the acquired organization about the new web address. To create a monitor, in the navigation pane expand Load Balancing, click Monitors and then click Add. This can avoid unauthorized users from gaining access to the network resources.
To create a configuration similar to the preceding procedure from the command line interface of the appliance, run following commands: To stop the back end server from sending compressed responses, it is recommended to delete the Accept-Encoding header by turning off the servercmp parameter.
The reason why the serverCmp parameter did not work is because the compression was not enabled on those services. Citrix is not responsible for inconsistencies, errors, or damage incurred as a result of the use of automatically-translated articles.
In this article, the following example is considered to explain the procedure of rewriting URL. Example To access a website, a user enters the following URL in the web netscaler rewrite action http to https Instructions Complete the following procedure to use the Rewrite feature of NetScaler appliance to change the hostname and URL in the client request: The NetScaler cannot rewrite if there are compressed responses from the back netscaler rewrite action http to https server.
In the Destination IP field, specify the In the traces, it is observed that the Accept-Encoding header is still going to the back end because the Content-Encoding: Problem Cause The trace analysis revealed that the back end server was sending compressed responses.
So even for the default no compress policies, we do not delete the accept-Encoding header even if compression is enabled on the service.
In this scenario you can use the Rewrite feature of the NetScaler appliance to change the hostname and URL in the client requests for the website of the acquired organization, appropriately. Compression can be turned off at the back end by making sure the Accept-Encoding header is not sent to the back end server when the request is forwarded to the NetScaler.
This option is deprecated in NetScaler version Citrix is not responsible for inconsistencies, errors, or damage incurred as a result of the use of automatically-translated articles. Citrix provides automatic translation to increase access to support content; however, automatically-translated articles may can contain errors.
Type 80 in the Port field. The only time the servercmp parameter kicks in is if compression is active on that particular service and NetScaler thinks it can compress the object, then it removes the accept-encoding header.
Delete the Accept-Encoding header by adding a rewrite action and policy: Instead of dropping the request, you might want to redirect the request to the secure Web site.
Specify 80 in the Port field. Citrix provides automatic translation to increase access to support content; however, automatically-translated articles may can contain errors. The navigation paths and screen shots are derived from NetScaler The status of the port 80 Load Balancing Redirect virtual server must be UP for the redirect to work.
A rewrite policy ensures that accept-encoding header is deleted for all requests that meets the specific criteria. This option is not present from NetScaler Click the Policies tab.
From the Action list, select the action name that you have created. Create a secure Load Balancing virtual server that has the IP address of the web site and port as Enable the Responder feature on the appliance if not already enabled.
A rewrite policy to delete the accept-encoding header is a better solution than turning off the servercmp parameter because there are still other situations when the NetScaler does not delete the accept-encoding header even if compression is enabled.
The following is an example of the action: For compressed responses the solution is to turn off compression on the back end and turn it on at the NetScaler. Additional Resources Troubleshooting Methodology The trace analysis revealed that the back end server was sending compressed responses.The rewrite policy for converting HTTP links to HTTPS does not work.

Additional Resources. Rewrite refers to the rewriting of some information in the requests or responses handled by the NetScaler appliance. Rewriting can help in providing access to the requested content without exposing unnecessary details about the Web site's actual configuration.
In this scenario you can use the Rewrite feature of the NetScaler appliance to change the hostname and URL in the client requests for the website of the acquired organization, appropriately. Also, use this feature to change the URLs in the client request temporarily when the website is under maintenance.
This article contains differences between the URL transformation and HTTP body rewrite features when configured on a virtual server of a NetScaler appliance.
The examples in this section demonstrate how to configure rewrite to perform various useful tasks.
The examples occur in the server room of Example Manufacturing Inc., a mid-sized manufacturing company that uses its Web site to manage a considerable portion of its sales, deliveries, and customer support.
