Apex application through Apache 2 proxy server on Backtrack 5

Apex application through Apache 2 proxy server on Backtrack 5

To start Apache 2:

/etc/init.d/apache2 start

Default, web document path:

/var/www

Your domain www.mydomain.com

Oracle XE comes with the embedded plsql gateway (in the database DBMS_EPG) and the "usual" HTML DB installation uses an Oracle Apache with mod_plsql. 
I would suggest using your Apache as a proxy to your XE installation.

/etc/apache2/httpd.conf

This is a pretty basic Apache feature – first you will need to load the required modules:

LoadModule proxy_module modules/mod_proxy.so

LoadModule proxy_http_module modules/mod_proxy_http.so

LoadModule rewrite_module modules/mod_rewrite.so

Let’s assume that I want to access a file at http://apexdomain.com/apex/f?p=... You would put all of the following into a :

# start mod_rewrite

RewriteEngine On

ProxyRequests Off

Order deny,allow

Allow from all

ProxyPass /sample/ http://apexdomain.com/apex/

ProxyPassReverse /sample/ http://apexdomain.com/apex/

RewriteRule ^/sample/(.*)$ /apex/$1 [R]

ProxyPass /i http://apexdomain.com/i

ProxyPassReverse /i http://apexdomain.com/i

Restart Apache and make a browser request to http://mydomain/sample/f?p=101:1 and you should receive a response from the remote server athttp://apexdomain.com/apex/f?p=101:1. The RewriteRule will pass along any query-string parameters too.

Full content of httpd.conf file may look like this:

#-------------------httpd.conf content -----------

DocumentRoot /var/www

ProxyRequests Off

Order deny,allow

Allow from all

LoadModule proxy_module modules/mod_proxy.so

LoadModule proxy_connect_module modules/mod_proxy_connect.so

LoadModule proxy_http_module modules/mod_rewrite.so

LoadModule proxy_http_module modules/mod_proxy_http.so

ServerName mydomain.com

ServerAlias myalias

RewriteEngine On

ProxyPass /samples/ http://apexdomain.com/apex

ProxyPassReverse /samples/ http://apexdomain.com/apex

RewriteRule ^/samples/(.*)$ /apex/$1 [R=301,L]

ProxyPass /i http://apexdomain.com/i

ProxyPassReverse /i http://apexdomain.com/i

#ProxyPass /sys http://apexdomain.com/sys

#ProxyPassReverse /sys http://apexdomain.com/sys

SetEnv force-proxy-request-1.0 1

SetEnv proxy-nokeepalive 1

CacheEnable disk /

CacheRoot "/var/cache/mod_proxy"

#------end of doc--------

To restart Apache 2:

/etc/init.d/apache2 restart

If it gives error that proxy.so modules are not launched.

Enable mod_proxy

proxy.so

proxy_connect.so

proxy_http.so

How to check module if it is already available?

Module path :
ls -l /usr/lib/apache2/modules/mod_proxy.so

Module config path :
ls -l /etc/apache2/mods-available/proxy.load

How to Enable mod_proxy now?

a2enmod proxy

a2enmod proxy_connect

a2enmod proxy_http

Restart Apache
/etc/init.d/apache2 restart

Test you application, all URLs that is rewritten should work now!

If you get following error:

Forbidden

You don't have permission to access /samples on this server.

---

Apache/2.2.14 (Ubuntu) Server at My IP Port 80

Check out the logs.

vi /var/log/apache2/error.log

If you have sort of this error:

[error] [client IP] client denied by server configuration: proxy:http://apexdomain/apex/ Client denied by server configuration error in Apache

The solution might be to edit

The solution might be to edit:

vi /etc/apache2/mods-available/proxy.conf

and change it as:

AddDefaultCharset off

Order deny,allow

#Deny from all

Allow from all #.example.com

Now, restart apache:

/etc/init.d/apache2 restart

If following error appears:

[warn] NameVirtualHost *:80 has no VirtualHosts

do following;

# a2dissite default

Restart Apache, and if you still get:

"[warn] NameVirtualHost *:80 has no VirtualHosts"

Then enable the 'default' site:

# a2ensite default

FYI. Apache's configuration is split in several files like:

httpd.conf, apache2.conf, ports.conf, conf.d/*., (conf.d/virtualhosts)

If you have following error, that means the path is not rewritten correct.

Bad Request

The HTTP client sent a request that this server could not understand.

You might not see graphics and get following error:

Flash Security Error

AnyChart can not be launched due to Flash Security Setting violation.
