Need to use the special character "$" in an HTTP header name?

Hi guys,

 

 

I need to pass the client cert in an HTTP header to the backend server. I have a working iRule that does this perfectly (from DevCentral :D ), however I need to call the HTTP header "$WSCC" and $ is obviosuly a special character. When I use the iRule below, I get this error in the logs (which I totally understand):

 

 

TCL error: Rule test_cert - can't read "WSCC": no such variable while xecuting "HTTP::header replace $WSCC [X509::whole $the_cert]"

 

 

 

So how can I define an HTTP header called "$WSCC" (without the quotes)?

 

 

This is the current iRule:

 

 

when CLIENTSSL_HANDSHAKE {

 

set cur [SSL::sessionid]

 

set ask [session lookup ssl $cur]

 

if { $ask eq "" } {

 

session add ssl [SSL::sessionid] [SSL::cert 0]

 

}

 

}

 

when HTTP_REQUEST {

 

set id [SSL::sessionid]

 

set the_cert [session lookup ssl $id]

 

if { $the_cert != ""}

 

{

 

HTTP::header replace $WSCC [X509::whole $the_cert]

 

log "Client cert is $the_cert"

 

}

 

else { log "no client cert found!" }

 

}

 

 

 

Thanks,

 

Risky.
