HTTP Respond and Redirect Together

Hi -

 

I need to be able to send an HTTP 404 along with a redirect. Can this be done? Why I want to do this... My OOS page is hosted externally. Currently I have an iRule that will send a 404 with content that is src="http://myoospage.othersite.com" This doesn't work for ssl connections, though, because it's attempting to use insecure content.

 

Any suggestions? I'm thinking if I can respond with a 404 and redirect that would work. The 404 response is a requirement.

 

Thanks!

    Maybe something like this...

    when HTTP_RESPONSE {
if { ([HTTP::status] equals "404") } {
    HTTP::respond 404 content " "
    }
}

    Sorry, it didn't like the html tags. Anyway, you could send the 404 back to the client that includes an html redirect such as meta http-equiv=refresh content=0;url=[destination_url]

      Hey Tim, So this worked...kind-of :) It only works when hitting the site using Firefox. Chrome just spits out what I have in quotes IE loads the page partially. I'm a bit of a novice here... any ideas on what else I may need? Here's my iRule as it looks now: when HTTP_REQUEST { if { ([active_members [LB::server pool]] < 1 ) } { HTTP::header insert Edge-Control bypass-cache HTTP::respond 404 content " " } }

      oops, tags got me too... In quotes I have the following with the brackets replaced with http://mystatus.othersite.com meta http-equiv=refresh content=0;url=[destination_url]

      You'll need to add all the opening and closing html tags, such as... html head meta http-equiv=refresh content=0;url=[destination_url] head html

    Which when added together becomes;-

        when HTTP_REQUEST {
        set 404_page " " 

    if {![active_members [LB::server pool]]} {
        HTTP::respond 404 content $404_page Edge-Control "bypass-cache" Cache-Control "nocache"
        return
    }
}

    OR

        when HTTP_RESPONSE {
        set 404_page " " 

    if { [HTTP::status] == 404} {
        HTTP::respond 404 content $404_page Edge-Control "bypass-cache" Cache-Control "nocache"
        return
    }
}

    Thanks Tim K! It works.

     

    Final iRule is like this: when HTTP_REQUEST { if { ([active_members [LB::server pool]] < 1 ) } { HTTP::header insert Edge-Control bypass-cache HTTP::respond 404 content " " } }
