CumulonimbusHow to stop an APM variable converting string to number
Hi all,
For a specific requirement, I need to add ".0" at the end of a username in APM. I'm doing this using a Variable Assign agent in the VPE.
As the username consists completely of numbers, APM automatically converts the variable to floating point number. Normally not a big problem as it's still stored in strings anyway, but unfortunately a lot of the usernames starts with one or more 0's, meaning during the conversion to floating point, it removes those leading zeroes! (...talk about APM/TCL being too helpful... ;)
Does anyone know of a way to force APM to interpret a variable and any modifications on it as strings, rather than numbers?
Thanks!
Hello Alex.
This is working for me:
session.logon.last.username = expr { "[mcget {session.logon.last.username}].0" }Regards,

AlexBCTHi Dario,
Thanks for the response!
I've just tried this one in my lab, but unfortunately it still strips off the leading 0 when I look at session.logon.last.username afterwards. When you run it with for example 012346 as a username, what does the variable look like afterwards in your system?
Thanks!
Hello Alex.
Apply this iRule to your VS.
when ACCESS_POLICY_AGENT_EVENT { if { [ACCESS::policy agent_id] eq "format_username" } { ACCESS::session data set session.logon.last.username "[ACCESS::session data get "session.logon.last.username"].0" } }Then configure an iRule Event box in your APM policy with ID "format_username".
Let me know if this works in your scenario.
Regards,
Dario.
