Check fastest server and using it
hello
we have upload some data in 15 servers in usa asia ...
i consider to add new feature , script can detect download speed between localhost and destination and use fastest server,

i have cut this part from a script which have this feature, download a xx MB file from all its source and check speed, and use fastest one:

Code:
echo -n "Would you like to search for the fastest download mirror? (y/n): ";
                read yesno;
                if [ "$yesno" = "y" ]; then
                    $BUILD set_fastest;
            
            if [ -s "${CB_OPTIONS}" ]; then
                DL=`grep ^downloadserver= ${CB_OPTIONS} | cut -d= -f2`
                if [ "${DL}" != "" ]; then
                    SERVER=http://${DL}/services
                    FTP_HOST=${DL}
                fi
            fi

SCRIPTS

       httest is script based. The following script examples can be but into a scripte i.e. sample.htt and can be called like

       httest sample.htt

SIMPLE SCRIPT

       Get a page and do expect return code 200 OK.

       CLIENT
       _REQ www.google.ch 80
       __GET /search?q=apache HTTP/1.1
       __Host: www.google.ch
       __
       _EXPECT headers "HTTP/1.1 200 OK"
       _WAIT
       END

CUT AND PAST SCRIPT

       Cut and past from a HTTP stream, i.e we cut the apache host to access it in the second request.

       CLIENT
       _REQ www.google.ch 80
       __GET /search?q=apache HTTP/1.1
       __Host: www.google.ch
       __
       _MATCH body '<a href="http://([^/]*)/" class=l>Welcome! - The <em>Apache</em> HTTP Server Project' APACHE_HOST
       _WAIT

       _REQ $APACHE_HOST 80
       __GET / HTTP/1.1
       __Host: $APACHE_HOST
       __
       _WAIT
       END

CLIENT SERVER SCRIPT

       We can hold client and server in the same host. Actually multiple client and multiple server.  Very useful to test forward or reverse prox-
       ies. Or a webapplication which communicat itself with third party servers i.e. mail server.

       This is a very basic selfcontained test you can run on any maschine.

       CLIENT
       _REQ localhost 8080
       __GET /foo HTTP/1.1
       __Host: localhost
       __
       _WAIT
       END

       SERVER 8080
       _RES
       _EXPECT "/foo"
       _WAIT
       __HTTP/1.1 200 OK
       __Content-Length: AUTO
       __
       __Hello World
       END

SSL SCRIPT

       Of course SSL do also work with httest, just put "SSL:" before port.

       CLIENT
       _REQ localhost SSL:8080
       __GET /foo HTTP/1.1
       __Host: localhost
       __
       _WAIT
       END

       SERVER SSL:8080
       _RES
       _EXPECT "/foo"
       _WAIT
       __HTTP/1.1 200 OK
       __Content-Length: AUTO
       __
       __Hello World
       END
