A10 has excellent performance, so we can migrate the reverse proxy that would have been implemented using the server to install Apache or nginx to this device.

The meaning of reverse proxy: the physical network has only one public network address, and multiple domain names point to this address (port 80), and these domain names correspond to multiple application servers of one server or multiple application servers of multiple servers. In this way, the reverse proxy implements "distribution" and returns the correct application to the terminal.

This time, the "reverse proxy" will be migrated to A10. The configuration process is as follows:

In configuration mode, SLB- template-App-HTTP

Add a new template

Click "Application Transformation" configuration interface, select "Host" according to "selection", add configuration at "URL conversion" configuration, for example, fill in www.a.com for URL, select pre-configured service group for service group, select default value (including) for matching type, click "add", and also fill in www.b.com, www.c.com, etc. In this way, bind this http template to the port of the virtual server (for example, when sharing port 80, add port 80, note that the type is selected as "HTTP", check "use the default server option when the priority selection method fails" and "use the received hop as a response" two options, select the configured "source NAT pool", and "HTTP template" select the template just built).

The problem found at present: if the target address is Apache or CentOs, it is OK to proxy again, but if the http header judged by IIS is not good, the current solution is to make all the sites into ports on iis instead of sharing 80, and then use A10 to point to each port.
