hello, everyone. I got a problem when I use mod_headers with apache.
my apache was configure as "./configure --enable-so --enable-rewrite --enable-proxy --enable-headers" to enable headers, and my server is config with:
Listen 10080
NameVirtualHost *:10080
<VirtualHost *:10080>
ServerAdmin webmaster@localhost
DocumentRoot "/usr/local/rzrq_proxy"
<Directory />
Options FollowSymLinks
AllowOverride None
</Directory>
<Directory /usr/local/rzrq_proxy>
Options Indexes FollowSymLinks MultiViews
AllowOverride None
Order allow,deny
Allow from all
</Directory>
ServerName rzrq_proxy
ErrorLog "/usr/local/apache2/logs/rzrq_proxy_error_log"
CustomLog "/usr/local/apache2/logs/rzrq_proxy_access_log" common
RequestHeader set USER "TestUser"
Header set REMOTE_USER "remote-user"
#ProxyRequests Off
#ProxyVia On
#<Proxy *>
#Order deny,allow
#Allow from all
#</Proxy>
#ProxyPass / http://192.168.188.156:8000/
#ProxyPassReverse / http://192.168.188.156:8000/
</VirtualHost>
when i started server and sent visit the 10080 port, the request header and reponse header is show like:
REQUEST:
GET / HTTP/1.1

i think only the Header directive enabled, and RequestHeader directive is not.

Red Hat Enterprise Linux Server release 5.3
Apache 2.2.21, 2.0.50 |

I think your problem is that you override that header with the second one. AFAIK you should use append instead if set for the second header. |

I change the header "USER" by another word like "X-USER-OTHER", and can't got in the browser's debug tools like firedebug(Firefox) or httpwatch(IE) debug infomation. Is the header set by RequestHeader can't be caught by browser's debug tools? Was the header sent before or after rebuild by browser? or just the version of apache? thank you! |

You can't view with a normal debugger, cause it is on the server side. In a php script you can see it with
| Code: |
echo $_SERVER["HTTP_USER"];
|
in a log file you might see it with
%{USER}i or %{HTTP_USER}i
Back to your question: with your posted config it works, but the RequestHeader will not send to the client. |

OK,
within PHP you can try
apache_response_headers()
and
apache_request_headers()
works only if you run PHP as module in apache. |
