Netscaler Content switching and websockets.

Does Citrix Netscaler support content switching and websockets?

[Ronan OBrien1709151594]

It depends on the type of protocol you choose for your Content Switch VServer. 

If you choose HTTP or SSL, then you can do content switching using those L7 policy expressions like "http.req.URL.contains("somevalue") to send traffic with "somevalue" in the URL to a specific Load Balanced VServer for HTTP or HTTPS requests.

 

However, once traffic starts to traverse the CS VServer using WebSockers, those L7 policies wont be evaluated. You can write TCP CS Policies, but they are a bit trickier. 

There are a few more options that you might need to discuss with support, or a partner, to achieve what you want using some other tools or features on the ADC.

What i want to do is use the netscaler as a reverse proxy server and use only one IP for multiple sites.
One sites is using websockets now.

Is this possible with netscaler?

[Mihai Cziraki1709160741]

as far as i know yes.

You only needs to enable wesockets in the http profile. I would create a custom one and apply to the vip.

If the client what's the http sessions to be upgraded to websockets the vip will use websockets.

I know that you can set the "Enable Websocket connections"

But i also want only one IP address for all my websites.
I can do this with content switching but content switching does not support websockets.

Do i need to create a VIP with a IP address for every website that uses websockets?
So when i have 5 websites that use websockets i need 5 different IP's?

[Mihai Cziraki1709160741]

as far as i know you can do content switching , but only before the connection is upgraded to websocks, after that it is not possible.

you could create  multiple vips(5 vips i guess in your case) with the same ip but with different ports.(80,8080.8081,etc)

Are websockets on content switching on the roadmap for Netscaler?
