[OpenSIPS-Users] trying to rewriteuri to the value of a variable

[Dave Singer]

Last week I ran into a similar thing with force_socket(). I was trying
to setup to force it out the second IP on the server and have it
generic for two load balanced servers. I did if ( $Ri == "<server 1's
IP>" ) { force_socket("<server 1's second IP>:5060"); } else {
force_socket("server 2's IP>:5060"); }
Interesting that config file check didn't catch the "error" but when I
started it up for "real" it displayed an error and stopped running.
It is a good thing I had my 2nd level config check implemented on
there where I run it listening on a local interface and dummy port. It
failed that test so it didn't actually restart opensips. (FYI: I
poseted my init.d script a while back)
It took me a while to realize $fs was there and made things sooooooo
much better.

We need to document for the functions like rewriteuri where there are
alternative variables like $ru, $du, $fs that that the variables are
available and the difference between the two. Maybe even depricate the
less feature-full functions unless there is an advantage like
performance.
