Using CSW to redirect request to a different URL/domain

by on ‎05-09-2009 10:14 AM (1,058 Views)


We want to redirect incoming traffic with a specific URL to a different domain.

This feature will typically be needed by websites who have spinned off some  of their content to another domain.

For example, support section of Company has been moved to a new location and we want to redirect any incoming  request to the new location


We will need Layer 7 switching in this case because we will use a match condition by matching anything starting with "/support" in the URL.

The redirect action takes three arguments:

1. the new domain-name

2. the new URL

3. the new protocol/port

We will modify the domain name to  "", and the URL to "/". We will leave the protocol/port  number as it is.

The following is a sample packet trace after applying the configuration.

Incoming request:

GET /support HTTP/1.1\r\n


User-Agent: ELinks/0.9.2 (textmode; Linux; 90x30)\r\n

Accept: */*\r\n

Accept-Encoding: bzip2, gzip\r\n

Accept-Language: en\r\n

Connection: Keep-Alive\r\n


Redirect which is getting send to the client:

HTTP/1.1 302 Moved Temporarily\r\n


Connection: close\r\n

Content-Length: 0\r\n
