favicon troubles keeps resulting in http 302 redirect

Hi, I understand this appears to be a little weird, so let me explain.. The purpose of this irule is to redirect users to a sub location www.x.com/north/something. Because that's the location of the application. There are two applications on two locations north and south. www.x.com is actually nothing. Furthermore we want to do a redirect when there are no available pool members to avoid "hard" error messages.

OK, understood, however, you have opposing logic in your rule, for instance a path of

/north/index.html

 if { !($RequestedPath starts_with "/n") }  {
        HTTP::redirect "https://x/north/" }

and

if { $RequestedPath contains "/north" } {   
 if {[active_members Pool_x-north] > 0 }      {
     pool Pool_x-north

There's is a difference in this irule i didn't explain correctly. The locations are world-north and world-south So the redirect should be something like this:

if { !($RequestedPath starts_with "/world") }  {
        HTTP::redirect "https://x/world-north/" }

This is the preferable location above south

After that we want to select a pool if there are active members.

if { $RequestedPath contains "/world-north" } {   
 if {[active_members Pool_x-north] > 0 }      {
     pool Pool_x-north

Sorry but that would still create a problem. If the path starts with /world, redirect to /world-north, the request comes back in with /world-north, which starts with /world, gets redirected and on...

What do you suggest?

I'm sure I could knock something up pretty quicky, can you just describe in detail exactly what you require please.

We'd like something as follows:

-> Begin with www.x.com

if someone types www.x.com/north goto www.x.com/north/applicationurl if someone types www.x.com/south goto www.x.com/south/applicationurl if someone types www.x.com/north/ goto www.x.com/north/applicationurl if someone types www.x.com/south/ goto www.x.com/south/applicationurl

if someone types just www.x.com goto www.x.com/north/applicationurl

When there are active pool members in north -> select north pool else -> produce fancy error page When there are active pool members in south -> select south pool else -> produce fancy error page

That's it basically..

OK, here you go, it's not too different but I've tidied up the switch and added some returns to prevent any logic clashes, plus added a reject where there's no match;

-REMOVED - CORRECTED BELOW

Thank you very much for this! Err.. I cannot appy the irule keeps struggeling about this syntax:

else {
   if { [active_members Pool_www.y.nl] > 0 } {
    HTTP::redirect "http://www.y.nl/error/"

Ah, I see the issue, corrected version;

when HTTP_REQUEST {
 set RequestedPath [string tolower [HTTP::path]]

 Redirect only if the HTTP path exactly matches one of the following; 
 switch $RequestedPath {
  "/" - 
  "/north" - 
  "/north/" {
   HTTP::redirect "https://x/north/applicationurl"
   Stop processing the iRule here
   return
  }
  "/south" - 
  "/south/" {
   HTTP::redirect "https://x/south/"
   Stop processing the iRule here
   return
  }
 }


 if { $RequestedPath starts_with "/north/" } {   
  if { [active_members Pool_x-north] > 0 } {
   pool Pool_x-north
  }
  elseif { [active_members Pool_www.y.nl] > 0 } {
   HTTP::redirect "http://www.y.nl/error/"
  }
 }

 elseif { $RequestedPath starts_with "/south/" } { 
  if { [active_members Pool_x-south] > 0 } {
   pool Pool_x-south
  }
  elseif { [active_members Pool_www.y.nl] > 0 } {
    HTTP::redirect "http://www.y.nl/error/"
  }
 }

 else {
   Can't serve fancy error page or HTTP path doesn't match
   Let's reject so clients don't have to wait for a timeout
   reject
 }
}
