[users@httpd] rewrite or proxypass?

Hi,

I don't exactly know if this is a rewrite or proxypass or something  
else type of thing so
I was hoping someone could help.


I have a Tomcat app running on port 8080

I can get to it through

http://www.ourcompany.com:8080

it goes to a login page and the URL displays

http://www.ourcompany.com:8080/login

I would like to be able to just put in

http://www.ourcompany.com

and get

http://www.ourcompany.com/login

Could anyone help me with this?

Thanks.

Pat.

Thanks to

Axel-Stephane
Robert Jaeschke
and
solprovider

for helping with this.

Solprovider suggested running Tomcat on port 80 because nothing is  
running there
and that would be the easiest solution. I didn't want to do that  
because that might change.

The solution Robert suggested worked. I could have sworn I tried this  
but must have had something
different.

ProxyPass / http://www.ourcompany.com:8080/
ProxyPassReverse / http://www.ourcompany.com:8080/

Axel's suggestion is very similar but I got an error

Forbidden

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

This is his

ProxyPass http://www.ourcompany.com/ http://www.ourcompany.com:8080/
ProxyPassReverse http://www.ourcompany.com/ http://www.ourcompany.com: 
8080/

Can you tell me the difference and why his didn't work?

Thanks for your help.

Pat.

Could it possibly be this simple?? You probably want to have two virtual hosts, one for port 80 and one for port 8080. In the former, add the following lines:

ProxyRequests Off
ProxyPass http://www.ourcompany.com/ http://www.ourcompany.com:8080/
ProxyPassReverse http://www.ourcompany.com/ http://www.ourcompany.com:8080/

Refer to the mod_proxy documentation for more details.

You may need to rewrite links.

Re: [users@httpd] rewrite or proxypass?

Posted by so...@apache.org.

Where is the login homepage?  Where does it POST?
Where is the application?
What URLs do clients see?
How do those URLs reach the correct server/port?
How does the application send URLs usable by the client?

>From my understanding of your needs, only example.com:80 should be
accessible to clients.  You want to firewall port 8080 from clients.
Apache httpd on port 80 will proxy to port 8080.  Questions:
1. Are all requests using the proxy?  Why bother using a proxy?  (That
was my previous question.)
2. Does a virtual server name indicate using the proxy?  (app.example.com)
3. Do certain paths indicate using the proxy? (example.com/app/...)

Your current issue is the application is not aware of the proxy.
mod_proxy only rewrites request URLs.  You need to use one of the
following options:

1. Configure the application for use behind the proxy.  Something like:
ROOT_PREFIX = "http://www.example.com/app/"
The syntax will depend on the application and the abilities of the developers.

2. Use mod_proxy_html to rewrite the HTML sent by the application to
change every "http://www.example.com:8080/" to
"http"//www.example.com/app/".

I may have spoken a little too soon.

While the entries I used ..

ProxyPass / http://www.ourcompany.com:8080/
ProxyPassReverse / http://www.ourcompany.com:8080/

..work on the initial screen and the first screen after logging in
if I click on any that the 8080 shows up again in the URL?

Is there something else that needs to be added to pick that up each  
time?

thanks

Why not put the homepage/login page on port 80 and proxy the POST to
Tomcat?  Or are dynamic elements on the login page?

If everything will be served by Tomcat, why not run tomcat on port 80?

If you are using virtual servers, you should already have configured the proxy.

You have to use mod_proxy and those two lines to your conf:

ProxyPass / http://www.ourcompany.com:8080/
ProxyPassReverse / http://www.ourcompany.com:8080/
