using getfield to split up URIs

Martin,

Here is the documentation for getfield (from the BIG-IP Users Manual)

getfield

The getfield command splits a string on a character, and returns the string corresponding to the specific field.

The syntax of the getfield command is:

getfield

So, for your example, you'll want to use the HTTP::uri for the "string" value, a slash for the "split" value and value of 4 for the "field" (the first field will be empty since there is nothing before the split char).

when HTTP_REQUEST {
  set cust_id [getfield [HTTP::uri] "/" 4]]
  if { $cust_id equals "company1" } {
    pool company1_pool
  } elseif { $cust_id equals "company2" } {
    pool company2_pool
  }
}

If your uri's can be mixed case, you might want to throw in a "string tolower" in there to convert the HTTP::uri to lowercase before the comparison.

when HTTP_REQUEST {
  set cust_id [string tolower [getfield [HTTP::uri] "/" 4]]]
  if { $cust_id equals "company1" } {
    pool company1_pool
  } elseif { $cust_id equals "company2" } {
    pool company2_pool
  }
}

Good luck!
