I have a apache instance setup to reverse proxy an internal application. I have this working using mod_proxy, but the end result is a lack of images and other content due to hard coded paths in the application itself. I think I have two options.
Mod_Rewrite
Mod_HTML
The basic problem is this.
External site: http://external.customer.com (Port 80)
Internal site: http://internal.supplier.com:8080/testcustomer
I need to get apache to proxy the connection, but it must use the full URL when talking to the internal server internal.supplier.com:8080/testcustomer and paths must be rewritten so that images etc will render on the end client.
Can anyone give me some guidance here? help would be much appreciated.
Thanks
That may be becuse you have used absolute paths like src=/app/favicon.jpg and src=/app/icons/smiley.jpg......instead of relative paths like using src="favicon.jpg".
This problem can be solved by adding module mod_proxy_html which helps in parsing html.
Then LoadModule proxy_html in your httpd.conf and then add following directives :-
ProxyHTMLEnable On
OR
SetOutputFilter proxy-html
mod_proxy_hmtl has pre-requisite installs libxml2 and libxml2-devel.You can install it through yum.
If you could share your configuration file then may be we can help more.
I have apache 2.2 with mod_wsgi handling /
WSGIScriptAlias / "...wsgihandler.py"
I have followed instructions to setup static file handling with AliasMatches and a matching directory configuration.
The website is working fine.
How can I determine that static content is served by Apache and not via wsgihandler.py
working? The apache access log file doesn't help me, even when I set it to debug.
I've tried to intercept and read traffic between Firefox and the server, but that didn't enlighten me either.
Work out what the URLs of the static files are and then comment out the WSGIScriptAlias. The URLs should still work.
Note that in general you would not use AliasMatch but just Alias. You might want to provide the appropriate parts of the Apache configuration so it can be reviewed to see whether you are doing it in the best way.
This is my attempt:
load the headers_module
and in
Header set MyHeader "Static content served"
Apache 2.4 includes mod_proxy_html and that's great, it's catching all kinds of URLs inside the HTML coming back from the server and fixing them. But I've got a Seam app that sends back text/xml files to the client sometimes with fully qualified URLs that also need to be rewritten and mod_proxy_html doesn't fix them.
Apparently there was a mod_proxy_xml that used to exist separately from mod_proxy_html but Apache didn't include that. Is there a way to get mod_proxy_html configured to do the same thing? I need it to fix URLs in both the HTML and XML files coming back from a server.
Follow up:
I continue to fight with this and I've tried a few different solutions with no success including using mod_substitute (which somehow I'm configuring incorrectly because it never seems to substitute anything for anything) and using the force flag mod_proxy_html has to try and force it to do all files under a certain path.
This is an old question, but I just faced the same issue.
I tried with mod_proxy_html, compiled mod_proxy_xml, nothing worked.
#JonLin's suggestion is spot on, it works with mod_sed.
The only if is mod_sed is documented to work inside Directory nodes.
If you declare a Location though and do a SetOutputFilter instead of AddOutputFilter (which requires a mime type) it works beautifully.
The config that works is:
<Location "/">
SetOutputFilter Sed
OutputSed "s,http://internal:80,https://external.com,g"
</Location>
I just installed a fresh copy of Drupal 6.19 to get to speed on how to write modules. But for some reason the rewrite module isn't working for Drupal.
What I have checked:
$ apachectl -M >> it is installed
php_info() on current server >> says rewrite is installed also
I also double-checked the .htaccess file in my Drupal root folder
UPDATE: checked httpd.conf for AllowOverride All
I'm out options here. Looked everywhere but the Drupal settings aren't letting me to enable the settings and their test is simply visiting a site that should work if the rewrite module was there.
My specs:
Mac OS X 10.6 Snow Leopard
Using built-in Apache with PHP5
Thanks!
Last but not least, you must authorize your virtual host or directory to use .htaccess.
AllowOverride All
Update:
I can't figure out your exact problem but it's always worth testing that Apache is actually parsing your .htaccess file. Make a syntax error on purpose and see if you get a 500 Internal Server Error message. Also, test mod_rewrite with a simple redirection rule that doesn't involve Drupal.
Two more things to check:
Verify that your .htaccess is readable for your apache processes (Yes, I read that you double checked it, but did that include the file permissions?)
Enable rewrite logging - this might give you some hints on where it fails. Start with a log level of 5 and increase/decrease as needed. (Don't forget to turn it off again later, as it is a huge performance hog ;)
Also, I'd try to simplify the test scenario - start with a simple rewrite directive in a vhost configuration. Once that works, move it to a .htaccess in the top-level of the vhosts document root, then to sub directories (if needed/used).
Make sure that if the install is in a sub-directory that the username is part of the rewriteBase
# Modify the RewriteBase if you are using Drupal in a subdirectory or in a
# VirtualDocumentRoot and the rewrite rules are not working properly.
# For example if your site is at http://example.com/drupal uncomment and
# modify the following line:
RewriteBase /~username/drupal**
If you running your Drupal installation in a sub-folder like: example.com/drupal, then enable "RewriteBase /" in your .htaccess file, it might help you.
A clean url could be something like www.example.com/fisherman instead of www.example.com/data/pages/fisherman.php
Some installations of apache have clean URL functionality out of the box. There are 2 steps that need to be configured correctly for it to work.
Enable rewrite module
Allow .htaccess file overrides
Both steps require SSH root access to your server. So if you are on shared host this probably won't work for you. Open your terminal:
Enable rewrite module
To enable the rewrite module, you can type the following command
sudo a2enmod rewrite
Now type
sudo service apache2 restart
to enable the changes. You can check if it’s working by typing
sudo apache2ctl –M
A list will appear. Look for “rewrite_module”.
http://codeontrack.com/enable-clean-urls-apache/
Look for this Line in your httpd.conf file
#LoadModule rewrite_module modules/mod_rewrite.so
If commented
Just uncomment it restart apache server then try enabling in drupal administer Clean URL Section
I added the following to my .htaccess file and it was solved. My problem was specifically hapening with Rackspace / CentOS image
Options -MultiViews
As Álvaro G. Vicario mentioned, the first thing to do is at the top of the .htaccess file add something like ghfdiddfdjf which should throw an internal error. If it doesn't, you know the .htaccess file isn't being read. Mine wasn't, and I found the following fix:
In the etc/apache2/sites-enabled folder, there was a file called default-000. It was in this file that I changed AllowOverride All in 2 places in the file.
I have an Apache server installed on my windows machine using XAMPP. Now I'm trying to use a premade .htaccess file for one of my projects, but it doesn't seem to be seeing it. The project just totally ignores it, even though I've enabled mod_rewrite.
Any idea how I can troubleshoot this? I can't fix it if it just doesn't work and doesn't show me any errors.
Appreciate your help.
In your httpd.conf file, you must enable .htaccess overriding with AllowOverride for the directory where the .htaccess file is (or parent thereof). If it is set to 'None', the .htaccess files will be ignored.
