CirrusConcatenate two values into one
I need to ocncatenate two values into one variable and separate them by a :
Basically, I need to build a string/variable that looks like clientaddress:clientport. I've tried to enter this in the iRule:
set srctoken [concat [IP::addr] [TCP::client_port]]
However, when I try to save the iRule, I get an error that says [wrong args] [IP::addr]
Also, I can't seem to figure out what's the proper way to insert a ":" betweent he argument. If the client's IP address is 10.1.1.1 and destination port is 80, then I need to create a string that looks like 10.1.1.1:80
Any help is greatly appreciated.

- Oh, as to your second question, you can try just setting the variable, rather than using concat, if you want to add something in between the two values.
Something like this:set myVar [IP::client_addr] + ":" + [TCP::client_port] or set myVar "[IP::client_addr] : [TCP::client_port]"

i get a syntax error trying to do something like:
set myVar [IP::client_addr] + ":" + [TCP::client_port]
wrong number arguments.. i need to do the same.. create a single string without spaces with two constants and a variable
if $myhost is abcd
"string1" $myHost "string2"
so it is string1abcdstring2 would be the result

Hi Brad,
You can just put commands together in a quoted string:
set myVar "[IP::client_addr]:[TCP::client_port]"
For variables you can use curly braces to delineate the variable name:
set myVar "string1${myHost}string2"
