Apache to Tomcat forwarding not working properly

Applications Web Development
1

Hi,

I am facing some problem with Apache to Tomcat forwarding. I have Tomcat (6.0.18) behind Apache (2.2). I want to use �https' for receiving request from the client. This request, when forwarded by Apache to Tomcat, will use �http'. My application's name is �abc', which is deployed in Tomcat's webapps dir. Both Tomcat & Apache are on the same machine. There is one more requirement: When a user just types the IP, it should, by default, forward it to the application's (abc) login page i.e., both the below mentioned URL's should point to the same page.

https://IP/
http://IP:8080/abc

I added the following lines in the httpd.conf file:
-----------------------------------------------------
ProxyPass /abc http://IP:8080/abc/implement
ProxyPass / http://IP:8080/abc/implement
-----------------------------------------------------

Now there are two issues:
-----------------------------------------------------

  1. When I try to use the https URL (https://IP/), it opens up the login page but the images are not visible. If I try the http one (http://IP:8080/abc/), then the page works fine.

I thought of using the blank (appearing so) image's URL (https://IP/abc/abc/images/logo_login.gif >>> abc 2 times is not a typo; the deployed directory's name is �abc' & there is a dir named �abc' inside �abc') and see where it's pointing to. When I tried accessing it, it too was pointing to the same login page where http://IP:8080/abc/ OR https://IP/ are pointing.

These are few results that might help you to understand my problem:
https://IP/ (No logo; only the login page)
https://IP/abc/abc/images/logo_login.gif (No logo; only the login page)
(I have also noticed that whatever I append in the https URL after https://IP/abc/ it takes me to the login page with no image)

http://IP:8080/abc/implement (Works perfectly. Login page with logo)
http://IP:8080/abc/implement/abc/images/logo_login.gif (Login page with logo. I had no idea what this would display but at least I did not imagine that it would display �login + image')
http://IP:8080/abc/abc/images/logo_login.gif (Shows ONLY logo as it ideally should)

  1. If we use IE6 to open https URL, then a warning box pops-up before the login page appears (without images). This behavior is absent in IE8.

The warning message states �line 56 Object expected�.
-----------------------------------------------------

Can anyone please guide me?

Hi,

I am now able to see image as well on the login page. :slight_smile: My new ProxyPass settings are:
------------------------------------------
ProxyPass /abc/abc/images http://IP:8080/abc/abc/images
ProxyPass /abc http://IP:8080/abc/implement
ProxyPass / http://IP:8080/abc/implement
------------------------------------------
Please don't get confused with the 2 abc mentioned above in thr URL; one is the deployed application's dir name and the following abc is a dir just inside it.
Now the problem I am facing is that when I try to access either 'https://IP' or 'https://IP/abc', I see some a yellow icon at the bottom left of my browser. On clicking it, it says
-------------------------------------------
Webpage error details
User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET CLR 2.0.50727; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729)
Timestamp: Tue, 4 May 2010 09:22:02 UTC
Message: Object expected

-------------------------------------------
Also, when I enter inside the login page, I don't get a proper page; instead I see the actual code written on the browser's screen.
On the other hand, if I try the 'http' URL (http://IP:8080/abc/implement\), everything works fine without any error message, anywhere. Looks like there is still some problem with my Apache to Tomcat communication.
