I want to make my server is available at go.mysite.com. My port is 7088. At the Internet I found a guide (though for Minecraft servers), which describes how to do it, and how to redirect the port via DNS. There was a talk about the SRV record.

Can I make the same for SAMP (I'm talking about port forwarding) to the player simply type go.mysite.com in the client, and then I may have to go to the server?

That won't really work for a SA:MP server simply due to the fact they have to use the samp:// protocol, not HTTP/HTTPS.
