Subject Re: [users@httpd] Re-use of a Setenv directive
Date Wed, 20 Oct 2010 13:30:22 GMT
S├ębastien, hello. I don't have a solution for you but I'm waiting for a 
similar reply.

I hope the following helps:

 From my e-mail thread entitled, 'Setting CGI environment variables, 
dynamically, from httpd.conf leveraging exising variables':
...

2. Technique 2: setenv DAVESETENV "text"

Eric Covenor replied:

        setenvif is a bit more flexible:
        http://httpd.apache.org/docs/current/mod/mod_setenvif.html#setenvif

==> So I reckon you should look at setenvif, rather.

Question 2: Also, I've never gotten SetEnvIf to work, for example:

    SetEnvIf "LA-U:REMOTE_PORT"               "(.*)"           
    A_SETENVIF_LA_U_REMOTE_PORT=$1
    SetEnvIf ${LA-U:REMOTE_PORT}               "(.*)"           
    A_SETENVIF_LA_U_REMOTE_PORT_PERCENT=$1

    SetEnvIf "LA-F:REMOTE_PORT"               "(.*)"           
    A_SETENVIF_LA_F_REMOTE_PORT=$1
    SetEnvIf ${LA-F:REMOTE_PORT}               "(.*)"           
    A_SETENVIF_LA_F_REMOTE_PORT_PERCENT=$1

    SetEnvIf "ENV:REMOTE_PORT"               "(.*)"           
    A_SETENVIF_ENV_REMOTE_PORT=$1
    SetEnvIf ${ENV:REMOTE_PORT}               "(.*)"           
    A_SETENVIF_ENV_REMOTE_PORT_PERCENT=$1

    SetEnvIf "SSL:REMOTE_PORT"               "(.*)"           
    A_SETENVIF_SSL_REMOTE_PORT=$1
    SetEnvIf ${SSL:REMOTE_PORT}               "(.*)"           
    A_SETENVIF_SSL_REMOTE_PORT_PERCENT=$1

    SetenvIf %{OID("0.9.2342.19200300.100.1.1")} "(.*)"           
    A_SETENVIF_OIDTEST_WITH_PERCENT=3D$1
    SetenvIf OID("0.9.2342.19200300.100.1.1") "(.*)"           
    A_SETENVIF_OIDTEST=3D$1

Result:

    A_SETENVIF_ENV_REMOTE_PORT=""
    A_SETENVIF_ENV_REMOTE_PORT_PERCENT=""
    A_SETENVIF_LA_F_REMOTE_PORT=""
    A_SETENVIF_LA_F_REMOTE_PORT_PERCENT=""
    A_SETENVIF_LA_U_REMOTE_PORT=""
    A_SETENVIF_LA_U_REMOTE_PORT_PERCENT=""
    A_SETENVIF_OIDTEST="3D"
    A_SETENVIF_OIDTEST_WITH_PERCENT="3D"
    A_SETENVIF_SSL_REMOTE_PORT=""
      


If I receive an answer I'll let you know.

Cdlt, Dave
