pool down redirect problem

Ok thanks. I think I understand. It flows through and finds the /maintenance and applies that as the response, then it hits the pool_down and also tries to apply that as a response. Is that right?

I ended up making three irules. The first one isn't attached to anything it just initializes the global variables. The second one checks for the uri of /maintenance and then calls an "event disable all". The third one then corrects certificate errors and status of the pool. Is this a proper way to do it?

...iRule number one (not assigned)

when RULE_INIT {

set ::wwwqawait 10

set ::wwwqaprot "https://"

set ::wwwqahost "www.site.com"

set ::wwwqafail "/maintenance"

set ::wwwqapool "Test_POOL"

}

...iRule number two

when HTTP_REQUEST {

check to see if the URI of the request starts with /maintenance

if { [string tolower [HTTP::uri]] starts_with "$::wwwqafail" }

{

HTTP::respond 200 content blah-server-down

...redirects to wwwqahost in wwqawait seconds...

event disable all

}

...iRule number three

when HTTP_REQUEST {

check to make sure connection is secure

if { [TCP::local_port] != 443 }

{

HTTP::redirect $::wwwqaprot[HTTP::host][HTTP::uri]

}

make sure a short host (2-part) is a correct match for our certificate (3-part)

if { [string length [getfield [HTTP::host] "." 3]] == 0}

{

HTTP::redirect $::wwwqaprot$::wwwqahost[HTTP::uri]

}

make sure a long host is a correct match for our certificate

if { [string length [getfield [HTTP::host] "." 4]] > 0}

{

HTTP::redirect $::wwwqaprot[domain [HTTP::host] 3][HTTP::uri]

}

check to see if the pool is down. if so, redirect to the maintenance page

if { [active_members $::wwwqapool] < 1 }

{

HTTP::redirect $::wwwqaprot$::wwwqahost$::wwwqafail

}

end http request block

}

when HTTP_RESPONSE {

HTTP::header remove Server

}
