No its not using IIS...but after thinking about it - why not just use the LTM as you suggested...
I have this so far but have a question: Can I add multiple URL's to check in this irule e.g. in BOLD I have adstructure/ i want to add other sites that have a login.jsp or login\password locations...
when HTTP_REQUEST { if {
([HTTP::uri] starts_with "/adstructure") and ([matchclass [IP::remote_addr] equals $$IPAddressDataGroup]) } { HTTP::redirect "https://www.xxx.com/adstructure/xxx/login.jsp/index/index/" } else { HTTP::redirect "https://www.xxx.com/" } }
