How to use pycontrol to enable X-Forwarded-For for a list of HTTP Profiles?

If this is a one-time action (say, due to the outcome of an audit) you could change all your HTTP profiles by using a bash script. If you have a list of all the HTTP profiles that you want to change in a text file, you could use the following one-liner at the bash prompt:

for profile in $(cat http_profiles.txt); do tmsh modify ltm profile http $profile insert-xforwarded-for enabled ; done

I don't have a platform in front of me to fully test this, but it should work.
