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. It should be available again within the specified time period. For any questions, please contact $contact. " noserver Connection Close event disable all TCP::close } } when LB_FAILED { if { [virtual name] starts_with "/ITSS/" }{ set contact "your Regional Helpdesk" } else { set contact "Application Support () or your Regional Helpdesk" } HTTP::respond 503 content " Application Unavailable - company Application unavailable This application is currently not available. Please contact $contact. " noserver Connection Close event disable all TCP::close }
Enable event Processing after HTTP::respond
I currently have an iRule that responds directly from the F5 with the HTTP::respond event. However, I would also like other iRules which log request/response to fire but they are not. From my searches on DevCentral, it looks like invoking the HTTP::respond causes all other events to be bypassed. Is there any way to get around this so that the request/response are still logged correctly? I have tried surrounding the HTTP::respond with 'event enable' but that doesn't seem to help. Thanks!

Help needed: HTTP::respond does not add headers
I am struggling with HTTP::respond and adding headers. This is an outline of what I am trying to do: when HTTP_RESPONSE { Save response-headers for later use set headers "" foreach aHeader [HTTP::header names] { set headers [concat $headers $aHeader [HTTP::header value $aHeader]] } log local0. "Headers Saved: $headers" Fetch "x-http-statuscode" for later use if {[HTTP::header exists "x-http-statuscode"]} { set xhttpstatuscode [lindex [HTTP::header values x-http-statuscode] 0] } if {[HTTP::status] == 200 && [expr {$xhttpstatuscode != 200}]} { HTTP::respond $xhttpstatuscode -version [HTTP::version] content [HTTP::payload] $headers } } I can't get HTTP::repond to add the "original headers"! Help is appreciated!
