http redirect based on path and query strings

Hi Jim,

You can parse individual query string parameters and their values using URI::query:

I'm not sure what the most efficient way to handle the lookups would be though. Maybe you could always order the parameter values in the data group in the same order and then form the string to lookup in the same way.

For example, if you have a query string like:

param2=anothervalue&param1=avalue&param3=value3

you would parse the values for param1, param2 and param3, concatenate them and then do a lookup against the data group which has the param values combined in the same way:

set value [class match -value "[URI::query [HTTP::uri] param1]|[URI::query [HTTP::uri] param2]|[URI::query [HTTP::uri] param3]" equals query_string_parameters_dg]

Your data group would have the parameter values concatenated with pipes as well:

ltm data-group uri_to_pool_dg {
    records {
        anothervalue|avalue|value3 {
            data match1
        }
        anothervalue2|avalue3|value5 {
            data match2
        }
    }
    type string
}
