irule for virtual server to redirect to different pool

Hi,

If I help do I get a discount on my utilities? 🙂

Can you try this example which checks the combined host header and path values set to lower case to select the pool? The non-matching requests will use the virtual server's default pool.

when CLIENT_ACCEPTED {
 Save the name of the VS default pool
set default_pool [LB::server pool]
}
when HTTP_REQUEST {

switch -glob [string tolower [HTTP::host][HTTP::path]] {
"*mywebsite.com/util*" {
"*seattle.gov/util*" } {
pool spu-util-pool
}
default {
pool $default_pool
}
}
}

Getting error when trying to update.

 

 

01070151:3: Rule [spu-util-pool-redirect] error: line 2: [undefined procedure: LB::dmz-lgxdev-pool-http] [LB::dmz-lgxdev-pool-http] line 9: [undefined procedure: default] [default { pool dmz-lgxdev-pool-http }] line 13: [command is not valid in the current scope] [}]

 

 

This is what I entered

 

 

 

when CLIENT_ACCEPTED {

 

set default_pool [LB::dmz-lgxdev-pool-http]

 

}

 

when HTTP_REQUEST {

 

switch -glob [string tolower [HTTP::host][HTTP::path]] {

 

"*seattle.gov/util*" } {

 

pool spu-util-pool

 

}

 

default {

 

pool dmz-lgxdev-pool-http

 

}

 

}

 

}

[LB::server pool] will return the default pool on the virtual server, so you don't need to update the name or hardcode the pool name in the iRule. Just set spu-util-pool to the name of the pool you want to use for the matching requests.

I'm sorry for so many questions....I'm an irule dummy.

 

 

Does this look right?

 

 

when HTTP_REQUEST {

 

switch -glob [string tolower [HTTP::host][HTTP::path]] {

 

"*seattle.gov/util*" } {

 

pool spu-util-pool

 

}

 

 

}

No worries. Try exactly this:

when CLIENT_ACCEPTED {
     Save the name of the VS default pool
    set default_pool [LB::server pool]
}
when HTTP_REQUEST {

    switch -glob "[string tolower [HTTP::host][HTTP::path]]" {
        "*seattle.gov/util*" {
            pool spu-util-pool
        }
        default {
            pool $default_pool
        }
    }
}

I am so close..................I only get one error when I try to update.

 

 

01070151:3: Rule [spu-util-pool-redirect] error: line 11: [undefined procedure: default_pool] [default_pool ]

 

 

I have tried many [ and { but nothing seems to be good enough.

Sorry, I had a typo in the iRule above. I edited the post to fix it.
