uri limit count

There's few technical limits. However, from a management and performance point of view, I'd hope you're using Data Groups.

As Steve said, you can add the redirects as name=value pairs to a data group and scale it up to ~100,000 entries in current versions. The performance shouldn't be impacted significantly by higher numbers of entries as it's a hashed list.

You can use the class command to look up the requested URI and map it to the new URI.

i've never used data groups, looking at default groups list i see ip address, my uri's are

 

//sitename/uri-path1

 

//sitename/uri-path2

 

//sitename/uri-path3

 

etc....how would i use data groups..give me an idea and I can reseach and give it a try. I want to use best practrice.

 

Here is an untested example. Define the data group separately and then add the iRule to the virtual server.

 v10.x data group mapping old URIs to new URIs
 Define this in the GUI under iRules | Data Group List or 
 by merging this config into your existing config:
 
class uri_mapping_dg {
   {
      "/old_uri1" { "/new_uri1" }
      "/old_uri2" { "/new_uri2" }
   }
}

 v11.x data group:
ltm data-group internal uri_mapping_dg {
    records {
        /old_uri1 {
            data /new_uri1
        }
        /old_uri2 {
            data /new_uri2
        }
    }
}

 iRule which looks up the client requested URI to get a match
when HTTP_REQUEST {

log local0. "[IP::client_addr]:[TCP::client_port]: [HTTP::method] to [HTTP::host][HTTP::uri]"

 Check if URI starts with a URI from the mapping data group
set redirect [class match -value [HTTP::path] starts_with uri_mapping_dg]

if {$redirect eq ""}{
 Take some default action for URIs which do not match the data group?
log local0. "[IP::client_addr]:[TCP::client_port]: No match for [HTTP::uri]"
} else {
HTTP::redirect $redirect
log local0. "[IP::client_addr]:[TCP::client_port]: Redirecting to $redirect"
}
}
