NimbostratusiRule to redirect to home page if URI contains email address
Hey all,
We've gotten a request for an iRule on a system living on a legacy 10.x system (being decommed soon) that redirects to the home page if the URI contains an email address. If I were doing this in Apache, I'd do something like:
RewriteCond %{QUERY_STRING} "[_A-Za-z0-9-\+]+(.[_A-Za-z0-9-]+)(@|\%40)[A-Za-z0-9-]+(.[A-Za-z0-9]+)(.[A-Za-z]{2,})"
RewriteRule ^.*?.(html)$ / [F]
(Haven't tested that, just an example of where I'd start)
I see that regex's in iRules are frowned upon, but not sure how else to handle this. Any thoughts or examples would be appreciated.

May be something like this. I have not tested it and used the regular expression that you have in question . If regular expression match redirect to some page. More on regexp can be found on.

when HTTP_REQUEST { set uri [HTTP::uri] set result [regexp {[_A-Za-z0-9-\+]+(.[_A-Za-z0-9-]+)(@|\%40)[A-Za-z0-9-]+(.[A-Za-z0-9]+)(.[A-Za-z]{2,})} $uri] if($result) { HTTP::redirect "http://www.example.com/newlocation.html" } }

Are you sure of your Apache rewrite rule? For it does not look like a redirect to me.
Also is an e-mail address the only thing expected in the query string?
It is better to illustrate your requirement with an example, for the sake of clarity.

Here's an alternative one based on what I thought you wanted:
when HTTP_REQUEST { if { [HTTP::query] ne "" } { if { [regexp {\y[^@]+@[\w.-]+\.\w+\y} [HTTP::query]] } { HTTP::redirect "/" } } }
