NimbostratusCookie and URI irule not working?
We have some ltms with 10.2 that will need to match on a cookie and uri irule logic and doesn't seem to be working properly.
when HTTP_REQUEST { if { ([class match [HTTP::cookie "UserInfo"] contains companyX]) and ( not [string tolower [HTTP::uri]] contains "/serviceb/")} { pool SERVER1 } }
I noticed that the cookie logic works fine by itself, but when I add the "and" logic it doesn't work. I'm wondering if my configuration is correct?

Probably need to move brackets around like below.
when HTTP_REQUEST { if { ([class match [HTTP::cookie "UserInfo"] contains companyX]) and \ not ([string tolower [HTTP::uri]] contains "/serviceb/")} { pool SERVER1 } }Just a tip, when posting iRules. Select your code and then press Tab. It will format it nicely for you 🙂
JCMATTOS_41723Kevin,
Thx for you response. Is the \ after the "and" a typo?

Take the \ out of the iRule. I think Kevin meant that as an indicator that the statement was continued on the next line.

Another common use of backslash substitution is for line continuation: Continuing long commands on multiple lines. When a line ends with a backslash, the interpreter converts it and the newline following it and all whitespace at the beginning of the next line into a single space character, then evaluates the concatenated line as a single command:iRules Optimization 101 - 04 - Delimiters: Braces, Brackets, Quotes and more by Deb Allen

The \ is a continuation character. If you put the following line back on the same line you don't need it.
iRules/TCL is a bit quirky though. Sometimes it likes it and sometimes.... if its throwing errors then remove it.
