Re: [users@httpd] Re-use of a Setenv directive

[David (Dave) Donnan]

Oups my test cases weren't tidy.

from vhost443.conf:
       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-U:REMOTE_PORT}               "(.*)"          
       A_SETENVIF_LA_U_REMOTE_PORT_DOLLAR=$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 ${LA-F:REMOTE_PORT}               "(.*)"          
       A_SETENVIF_LA_F_REMOTE_PORT_DOLLAR=$1

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

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

       SetenvIf OID("0.9.2342.19200300.100.1.1") "(.*)"           
       A_SETENVIF_OIDTEST=3D$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_WITH_DOLLAR=3D$1


And the result from printenv.pl:

       A_SETENVIF_ENV_REMOTE_PORT=""
       A_SETENVIF_ENV_REMOTE_PORT_DOLLAR=""
       A_SETENVIF_ENV_REMOTE_PORT_PERCENT=""

I hope the following helps:

        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.

Hi

I have defined a SetEnv Directive this way:
    SetEnv BASE_PATH /tmp/smthg

I would like to re-use this variable in another SetEnv Directive, e.g.:
    SetEnv PATHS $BASE_PATH/a:$BASE_PATH/b:$BASE_PATH/c:...


But $BASE_PATH is not interpreted as a variable.
I tried with quotes, back-splash, ...


How can I re-use this variable in another SetEnv Directive ?
Thanks
