Subject [users@httpd] Apache Reverse Proxy Help - not getting correct URL for images
Date Wed, 14 May 2014 04:15:00 GMT
I have some error with my apache reverse proxy. Currently I am doing
reverse proxy to 4 websites.

   - 1.1.1.1/a
   - 1.1.1.2/b
   - 1.1.1.3/c
   - 1.1.1.4/d

I am having no problem when reverse proxy to a and b website. Image are
good and no problem.

However, when comes to c and d website. Image are not getting loaded.In my
access_log , here are the logs.

- - [08/May/2014:10:40:36 +0800] "GET

HTTP/1.1" 404 1245

Accessing from the apache reverse proxy server itself have no problem. When
accessing from outside, the problem occur.

I have try directly typing the url in another machine and the image are
loaded.

1.1.1.1 - - [08/May/2014:10:19:00 +0800] "GET
**/d/images_v3/footer/icon_share.png** HTTP/1.1" 200 869 "-"
"Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like
Gecko) Chrome/34.0.1847.131 Safari/537.36
1.1.1.1 - - [08/May/2014:10:18:24 +0800] "GET
**/images_v3/footer/icon_share.png HTTP/1.1" 404 1245**
"htt://1.2.3.4/digi/landing.do" "Mozilla/5.0 (Windows NT 6.1; WOW64)
AppleWebKit/537.36 (KHTML, like Gecko) Chrome/34.0.1847.131
Safari/537.36"

As you can see the link in the first one is working. The one in the second
one is not.

When I request the webpage normally, it will request the second link and it
will cause 404 error as cannot find the path.

If i type directly the first link , the image was found.

I notice that c and d website are redirected when type the link.And this is
the cause of the problem.

1.1.1.3/c --> 1.1.1.3/c/index_other.html 1.1.1.4/d --> 1.1.1.4/d/landing.do

Here is my apache reverse proxy configuration

<VirtualHost *:80>
    #ServerAdmin webmaster@dummy-host.example.com
    #DocumentRoot /www/docs/dummy-host.example.com
    #ServerName dummy-host.example.com
    ErrorLog logs/arp_error_log
    CustomLog logs/arp_access_log common

    ProxyRequests Off

        <Location /a>
                ProxyPass http://1.1.1.1/a
                ProxyPassReverse http://1.1.1.1/a
        </Location>

        <Location /b>
                ProxyPass http://1.1.1.2/b
                ProxyPassReverse http://1.1.1.2/b
        </Location>

        <Location /c>
                ProxyPass http://1.1.1.3/index_other.html
                ProxyPassReverse http://1.1.1.3/index_other.html
        </Location>

        <Location /d>
            ProxyPass http://1.1.1.4:8080
            ProxyPassReverse http://1.1.1.4:8080
         </Location>

</VirtualHost>

So , how do i solve this? I have been researching mod_rewrite and
mod_proxy_html , but no luck in solving the problem.
