[users@httpd] environment variables manipulation in httpd.conf
Hello,
I've just recompiled a apache 2.2.17 on linux with all
modules in shared. I'm trying to add headers containing apache
"environment variables" like SERVER_NAME, HTTP_USER_AGENT with
mod_headers.
I always get null in my headers.
The response from server contains the header but I'm
unable to put inside any env variables
The only thing that works is the %D and %t for time.
I'm probably missing something but I can not figure what
I'm doing wrong.
Here is an extract of th httpd.conf
LoadModule env_module modules/env_headers.so
LoadModule headers_module modules/mode_headers.so
LoadModule ident_module modules/mode_ident.so
LoadModule unique_id_module modules/mode_unique_id.so
LoadModule setenvif_module modules/mode_setenvif.so
LoadModule rewrite_module modules/mode_rewrite.so
ServerName Server
Listen 8080
Header add TOTO "%D %t %{SERVER_NAME}e"
NameVirtualHost *:8080
<VirtualHost *:8080>
DocumentRoot /usr/local/apache/htdocs"
ServerName Server
Header add TUTU "%D
%t %{SERVER_NAME}e"
</VirtualHost>
With this conf I get TUTU D=xxxxxx t=ttttttt null It is
the same with every variables. Same with headers TOTO. It is like the environment variables are not available outside a cgi programm
Thanks in advance

There is something very strange with these variables.
For example I can logged SERVER_NAME in the log file thus there is really something that I do not understand. How the same variable can be expansed for logging but in the same time be unavailable for creating a header...
I have not find any list in documentation describing the scope of availabilty of each variables. I do not have seen either a list of variable from apache docs. It seems to spread among the modules documentations

Modules like setenvif or mod_rewrite might might let you expose
various internal data as environment variables.
Does the manual say SERVER_NAME should be available in the environment?

Thanks for quick the response.
I do not have seen any explanation about the variables and when they are available in the documentation.
Is there any solution to have them available everywhere ie outside a cgi.
Regards

Should note that if the request is CGI or (mod_include which also sets
them) then the variables hang along enough to be logged as well.

This is the case for many environment variables.
