What to do after HTTP::respond ?
Hello, I currently have a maintenance-unavailable iRule that returns a HTML page when the vs is in maintenance mode (value in datagroup list) or is not available. (LB_FAILED) My first check is if the URI is an image that is linked to in the page. If yes, HTTP::respond with a Connection: Close header, disable all future iRule events & TCP::close. This seems a very hacky way of doing this. I manually close the TCP connection because for some apps, we have an IIS request forwarder in front of the bigip that may do connection pooling; event disable all would disable all iRules for all applications on that TCP connection. How are you all doing this? priority 50 when HTTP_REQUEST { if { [HTTP::uri] eq "/bip-company-logo.gif" }{ HTTP::respond 200 content [ifile get "company-logo"] noserver Content-Type image/gif Connection Close event disable all TCP::close return } if { [class match -value [virtual name] equals "maintenance-list"] eq "1" } { if { [HTTP::uri] eq "/favicon.ico" }{ HTTP::respond 404 noserver Connection Close event disable all TCP::close return } if { [virtual name] starts_with "/ITSS/" }{ set contact "your Regional Helpdesk" } else { set contact "Application Support () or your Regional Helpdesk" } HTTP::respond 200 content " Down for maintenance - company Maintenance This application is currently undergoing maintenance.
