Send Request To Pool If Certain HTTP_URI

I have a virtual server setup with a default pool. We have a third party appliance we want to use if anyone hits a certain subfolder of our site, www.site.com/products. There will probably be something after the products, so I need to rule to look for products and possibly anything after then send it to a different pool.

 

 

Here's what I have so far.

 

 

when HTTP_REQUEST {

 

if { [HTTP::uri] starts_with "/products" } {

 

pool Appliance.

 

}

 

}

 

 

I don't need to make any changes to the virtual server except for adding this iRule, right?

    Hi Fotios,

    You could write up in the following manner using the switch command. 

     
 when HTTP_REQUEST { 
    switch -glob [HTTP::uri] { 
     "/products" { pool appliance } 
     "/products/something" {pool something } 
     "/products/something/andsomething" { pool andsomething } 
    } 
 }

    If you need more info then do a search on this site for "SWITCH"

    I hope this helps

    I don't need anything that advanced. Basically, we have a search appliance that we're adding to our site under /products. The only question I had was, what if the uri is longer than just /products, it will still be picked up by this iRule, right?

    By making a small alteration in the irule you could

    I.E. 

     
 when HTTP_REQUEST { 
    switch -glob [HTTP::uri] { 
      "/products*" { pool appliance } 
    } 
 }

    One small wrinkle I found. If you're hitting the site under the /products* and you want to go back to the main site under the other pool, it doesn't seem to use that but rather stick to the appliance pool. Should I set the default pool, then change it based on the uri? Or could I reset the connection somehow?

    You should either explicitly set a pool for every case in the iRule if you're selecting a pool for any case, or add a OneConnect profile. See this post for details/testing examples:

     

     

    iRule Editor can't find default_pool
