Recursive HTTP redirection, why?

1. If I dont use the condition "if { not ([HTTP::uri] starts_with "/_layouts/nestlepages/markethome.aspx?")}" then i will get recursive HTTP 302 redirections, is it correct?yes

e.g.

[root@ve10:Active] config  curl -IL http://thenest-eur-de.example.com/something
HTTP/1.0 302 Found
Location: http://thenest-eur-de.example.com/_bla1bla2bla3?/something
Server: BigIP
Connection: Keep-Alive
Content-Length: 0

HTTP/1.0 302 Found
Location: http://thenest-eur-de.example.com/_bla1bla2bla3?/_bla1bla2bla3?/something
Server: BigIP
Connection: Keep-Alive
Content-Length: 0

...snipped...

HTTP/1.0 302 Found
Location: http://thenest-eur-de.example.com/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/_bla1bla2bla3?/something
Server: BigIP
Connection: Keep-Alive
Content-Length: 0

curl: (47) Maximum (50) redirects followed

2. do i need to bring all chars to lower case?if case is mixed, i think it is better to use string tolower before comparision.

Thank you very much for your valuable help!!

 

 

One last question. After I defined the HTTP redirection, shall i put the pool in the iRule itself or specify it in the LTM GUI?

 

 

I mean... i could add the line pool after the inner 'if'.....

.....

 

HTTP::redirect http://thenest-eur-de.example.com/_bla1bla2bla3?[HTTP::uri]

 

pool mypool

 

return

 

....

 

 

does it matter where i configure the pool? in the GUI or in the iRule?

 

HTTP::redirect http://thenest-eur-de.example.com/_bla1bla2bla3?[HTTP::uri]

pool mypool pool won't be executed because HTTP::redirect already send response to client.

by the way, if my_pool is already assigned to the virtual server, you can adjust the irule something like this.

when HTTP_REQUEST {
  if { [active_members [LB::server pool]] > 0 } {
    if { not ([HTTP::uri] starts_with "/_bla1bla2bla3?") } {
      HTTP::redirect "http://thenest-eur-de.example.com/_bla1bla2bla3?[HTTP::uri]"
    }
  } else {
    HTTP::redirect "http://whatever.com"
  }
}
