header substr

Hi Guys,

I have a header field coming from the http request.

X-Akamai-Edgescape: georegion=263,country_code=US,region_code=MA,city=CAMBRIDGE,dma=506,pmsa=1120,areacode=617,county=MIDDLESEX,fips=25017,lat=42.3933,long=-71.1333,timezone=EST,zip=02138-02142+02238-02239,continent=NA,throughput=vhigh,asnum=21399

at first i want to extract just country_code=US and save it in a var.

at second i want create a new header like x-test=$var

and finally i want to insert the new header to the original request and forward it to the back end system.

any ideas how i can achieve it?

Thanks 4 you help

    Try this

    when HTTP_REQUEST {
    if {[HTTP::header exists "X-Akamai-Edgescape"]} {
        set headerList [split [HTTP::header value "X-Akamai-Edgescape"] ,]
        set countryCode [lindex $headerList [lsearch -glob $headerList "country_code=*"]]
        HTTP::header insert "x-test" $countryCode
    }
}
