redirect and sorry server, new to irules

Hi Jamesy,

 

The examples you presented are not redirects, because redirects, specifically HTTP redirects is forcing the client's browser to go to a new link or URL. I think what you are refering to is send then the HTTP request to a specific pool based on certain conditions.

 

 

So let's start with following pseudo code

 

 

IF POOL A is unavailable {

 

then go to Pool B

 

ELSE

 

Go to POOL A

 

 

Now there is a command called active_members (http://devcentral.f5.com/wiki/default.aspx/iRules/active_members.html)

 

When executed this command returns the number of members in a pool So if all the servers in a pool is unavailable then it should return a zero.

 

 

Using one of your examples

 

 

when HTTP_REQUEST {
  if { [active_members pool1] > 0 } {
      if { [HTTP::uri] starts_with "/login-test" } {
         pool Pool1
          }
  } else {
        pool sorry_page_pool
  }
}

 

 

I hope this helps
