Variable Passing between Events

Hi !

 

 

I am sorry that I am a Newbie for iRule and Tcl command. Could anyone help me the following:

 

 

Why can't it pass the value of $clsub from Event CLIENTSSL_CLIENTCERT to event HTTP_REQUEST. How to solve it and what way can I use for solution?

 

 

 

when CLIENT_ACCEPTED {

 

set needcert 0;

 

set gotcert 0;

 

set crt "";

 

set clcert "";

 

}

 

 

when CLIENTSSL_CLIENTCERT {

 

log LOCAL0.warn "cert count=[SSL::cert count] result= SSL::verify_result]";

 

if { [SSL::cert count] != 0 or [SSL::verify_result] == 0 } {

 

log LOCAL0.warn "Good cert! ($needcert)"

 

set gotcert 1

 

set crt "[SSL::cert 0]"

 

set clsub "[X509::subject $crt]"

 

Subject is obtained successfully shown on log.

 

log LOCAL0. "$clsub"

 

if { $needcert == 1 } {

 

HTTP::release

 

}

 

} else {

 

log LOCAL0.warn "Bad cert!"

 

if { $needcert == 1 } {

 

reject

 

}

 

}

 

}

 

 

 

 

when HTTP_REQUEST {

 

log LOCAL0. "HTTP-RQ"

 

I found $clsub is null on log.

 

log LOCAL0. "$clsub"
