Config Sync issues surrounding iRule

HELP   I come form a Nortel/Alteon background and am very new to the use of iRules and am experiencing some issue when using a canned 404 file not found handler from the Devcentral iRule code share...

Hi Dave,

This looks like an issue described in CR73005, where un-escaped metacharacters in a rule are allowed per GUI or iRuler validation, but break the parsing of the bigip.conf file when it is loaded (as during a config sync). You should get an error or experience the same issue on the BIG-IP you're synching from, if you try to reload the config.

To get your rule to work on 9.4.3, I escaped the double quotes with a backslash and then wrapped the HTML in two un-escaped doublequotes:


set error_404 {"
"}

This allowed me to save and reload the rule. Don't ask why the outside double quotes worked... I haven't a clue.

I'd suggest you open a case with support on this, as the validation done when adding rules should match what the parser can handle.

Thanks,

Aaron
