Change a query parameter

Hi wadeziegler,

Can you try this?

when HTTP_REQUEST {
    if { [HTTP::query] contains "reversedmarker" } {
        set uri [HTTP::uri]
        set reversedmarkervalue [URI::query $uri reversedmarker]
        set markervalue "[getfield $reversedmarkervalue "," 2],[getfield $reversedmarkervalue "," 1]"
        set newuri [string map [list $reversedmarkervalue $markervalue "reversedmarker" "marker" ] $uri]
        HTTP::uri $newuri
        # for redirect
        # HTTP::redirect https://[HTTP::host]$newuri
        unset uri reversedmarkervalue markervalue newuri
    }
}

or shorter but less readable:

when HTTP_REQUEST {
    if { [HTTP::query] contains "reversedmarker" } {
        HTTP::uri [string map [list "[URI::query [HTTP::uri] reversedmarker]" "[getfield [URI::query [HTTP::uri] reversedmarker] "," 2],[getfield [URI::query [HTTP::uri] reversedmarker] "," 1]" "reversedmarker" "marker"] [HTTP::uri]]
        # for redirect
        # HTTP::redirect https://[HTTP::host][string map [list "[URI::query [HTTP::uri] reversedmarker]" "[getfield [URI::query [HTTP::uri] reversedmarker] "," 2],[getfield [URI::query [HTTP::uri] reversedmarker] "," 1]" "reversedmarker" "marker"] [HTTP::uri]]
    }
}
