Converting NGINX proxypass rule to iRule

Hi,

 

I have following nginx rule which I need to convert to F5 rule. I am very new to F5. It would great if someone can help me or give good pointer to some examples.

 

upstream x1{ server server1:8080; server server28080; } location /uri1/uri2/api/ { proxy_pass_header Set-Cookie; proxy_pass http://x1/myuri/api }

 

Thanks in advance

 

Cheers, Kandarp
