    Just one approach;-

    when HTTP_REQUEST {
    if {[URI::query [HTTP::uri]] contains "mykey="} {
        set newq ""
        foreach param [split [URI::query [HTTP::uri]] "&"] {
            if {!($param starts_with "mykey=")} {
                     Build up new query parameter string
                append newq $param
            }
             Add new query portion to path
            HTTP::uri "[HTTP::path]$newq"
        }
    }

For everyone benefit, here I wanted to share the final version. From the above script we failed to put & in between each key=value pairs. Here is the working script:

 

when HTTP_REQUEST { set newq ""

 

foreach param [split [URI::query [HTTP::uri]] "&"] { if {!($param contains "mykey=" )} { if {$newq eq ""} { append newq $param } else { append newq "&$param" } } } Add new query portion to path if {$newq ne ""} { HTTP::uri "[HTTP::path]?$newq" } else { HTTP::uri [HTTP::path] } }
