i am using apache web server on localhost:80 and geoserver served from jetty servlet on localhost:8888. i want to setup a proxy to redirect the requests such that requests to localhost/geoserver are routed to localhost:8888/geoserver

i am following tutorial from http://gistutor.com/geoserver/21-intermediate-geoserver-tutorials/38-configuring-geoserver-proxy-for-public-and-remote-data-access.html and i am stuck in the part where it says

copy the text below and right click to paste the ProxyPass into your httpd.conf file 
right above the </VirtualHost> tag.

ProxyRequests Off
ProxyPreserveHost On
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
ProxyPass /geoserver http://localhost:8080/geoserver
ProxyPassReverse /geoserver http://localhost:8080/geoserver

i cannot find where to insert above text in httpd.conf file. the virtual hosts directive in httpd.conf file points to httpd-vhosts.conf file which looks like below

#
# Use name-based virtual hosting.
#
##NameVirtualHost *:80

#
# VirtualHost example:
# Almost any Apache directive may go into a VirtualHost container.
# The first VirtualHost section is used for all requests that do not
# match a ServerName or ServerAlias in any <VirtualHost> block.
#
##<VirtualHost *:80>
##ServerAdmin postmaster@dummy-host.localhost
##DocumentRoot "C:/xampp/htdocs/dummy-host.localhost"
##ServerName dummy-host.localhost
##ServerAlias www.dummy-host.localhost
##ErrorLog "logs/dummy-host.localhost-error.log"
##CustomLog "logs/dummy-host.localhost-access.log" combined
##</VirtualHost>

##<VirtualHost *:80>
##ServerAdmin postmaster@dummy-host2.localhost
##DocumentRoot "C:/xampp/htdocs/dummy-host2.localhost"
##ServerName dummy-host2.localhost
##ServerAlias www.dummy-host2.localhost
##ErrorLog "logs/dummy-host2.localhost-error.log"
##CustomLog "logs/dummy-host2.localhost-access.log" combined
##</VirtualHost>

i have tried and changed this httpd-vhosts.conf file with above codes, but every time i do this i am unable to restart apache server.

this is the httpd.conf file as in c:\xampp\apache\conf\

#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# Do not add a slash at the end of the directory path.  If you point
# ServerRoot at a non-local disk, be sure to point the LockFile directive
# at a local disk.  If you wish to share the same ServerRoot for multiple
# httpd daemons, you will need to change at least LockFile and PidFile.
#
ServerRoot "C:/xampp/apache"

#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to 
# prevent Apache from glomming onto all bound IP addresses.

#Listen 0.0.0.0:80
#Listen [::]:80

What OS and what version of Apache are you using? Was able to proxy Geoserver but I edited the /etc/apache2/sites-available/default instead. –  R.K. Aug 20 '12 at 2:18
    
@R.K. i am using XAMPP 1.7.7 –  neogeomat Aug 20 '12 at 4:28

If you're using Ubuntu, you'll first have to configure Apache

$sudo ln -s /etc/apache2/mods-available/proxy.conf /etc/apache2/mods-enabled/proxy.conf
$sudo ln -s /etc/apache2/mods-available/proxy.load /etc/apache2/mods-enabled/proxy.load
$sudo ln -s /etc/apache2/mods-available/proxy_http.load /etc/apache2/mods-enabled/proxy_http.load

Then append the following to your /etc/apache2/sites-available/default

 ProxyRequests Off 
 # Remember to turn the next line off if you are proxying to a NameVirtualHost 
 ProxyPreserveHost On 

 <Proxy *> 
     Order deny,allow 
     Allow from all 
 </Proxy> 

 ProxyPass /geoserver http://localhost:8888/geoserver 
 ProxyPassReverse /geoserver http://localhost:8888/geoserver 

 </VirtualHost> 

It's a bit tricky in Windows, you'll have to load some modules to enable the proxy. In your httpd.conf, add the following:

LoadModule  proxy_module         modules/mod_proxy.so
LoadModule  proxy_http_module    modules/mod_proxy_http.so
#LoadModule proxy_ftp_module     modules/mod_proxy_ftp.so
#LoadModule proxy_connect_module modules/mod_proxy_connect.so
LoadModule  headers_module       modules/mod_headers.so
LoadModule  deflate_module       modules/mod_deflate.so
LoadModule  xml2enc_module       modules/mod_xml2enc.so
LoadModule  proxy_html_module    modules/mod_proxy_html.so

At the end of your httpd.conf add the following lines

<VirtualHost  *:80>
   ProxyPass /geoserver http://localhost:8080/geoserver
   ProxyPassReverse /geoserver http://localhost:8080/geoserver
</VirtualHost>

You do not need to configure proxypass and proxypassreverse.

You will need a proxy.cgi file written in python, and python installed on your server. you can get the proxy file with the openlayers distribution in the example folder. you will have to configure the path to python interpreter in the 1st line, and add your host to list of allowed hosts.
