Apache htaccess Custom ErrorDocument not working properly for root home page 403 Error Issue and Solution -

Apache htaccess Custom ErrorDocument not working properly for root home page 403 Error Issue and Solution

So I have a domain "testdomain.com".

Inside test domain.com's root is the following .htaccess:


Options +FollowSymLinks -Indexes
ErrorDocument 403 /launch/index.html

Order Deny,Allow
Deny From All
Allow From 192.168.1.2

When you visit anything other than root things work fine.  Eg. if you visit http://testdomain.com/somedirfile.html

It will show the right error in /launch/

But if you just visit the root you get the standard Apache Test page even though a 403 is returned.  The reason for this is because of an Alias "Error" in /etc/httpd/httpd.conf

Find this line and comment it out:

Alias /error/ "/var/www/error/"

What happens when visiting root is that it checks for a custom 403 error in /var/www/error/ and when it doesn't find one in there it returns noindex.html (the Apache test page).

However I don't know a better work-around what Apache then does after commenting out that alias is it insists in then looking inside your /www/document_root/error/ folder for a matching custom file.  If not it looks for a noindex.html in there.

So all I did was create a no index.html in an error folder within my document root.

This solves the issue but I am not sure of how to make a better solution.  I searched for hours modifying the vhost configuration but nothing worked or helped except the above.

These URLs below had the same issue:

Here is some of the troubleshooting process I went through:

 

I have an issue where I am only allowing a few IPs to view a website in .htaccess:


Options +FollowSymLinks -Indexes
ErrorDocument 403 /launch/index.html

Order Deny,Allow
Deny From All
Allow From 192.168.1.2


# Now it works if you go to http://url/somecrap it will take you to /launch/index.html
But if you just go to the reoot http://url/ or http://url you get the Apache Test page instead:

solution:
edit /etc/httpd/httpd.conf

# Customizable error responses come in three flavors:
# 1) plain text 2) local redirects 3) external redirects
#
# Some examples:
#ErrorDocument 500 "The server made a boo boo."
#ErrorDocument 404 /missing.html
#ErrorDocument 404 "/cgi-bin/missing_handler.pl"
#ErrorDocument 402 http://www.example.com/subscription_info.html
#

#
# Putting this all together, we can internationalize error responses.
#
# We use Alias to redirect any /error/HTTP_<error>.html.var response to
# our collection of by-error message multi-language collections.  We use
# includes to substitute the appropriate text.
#
# You can modify the messages' appearance without changing any of the
# default HTTP_<error>.html.var files by adding the line:
#
#   Alias /error/include/ "/your/include/path/"
#
# which allows you to create your own set of files by starting with the
# /var/www/error/include/ files and
# copying them to /your/include/path/, even on a per-VirtualHost basis.
#

#Alias /error/ "/var/www/error/"


[root@serverdev error]# mv noindex.html noindex.html-bad
[root@serverdev error]# readlink -f .
/var/www/error


Alias /error/ "/var/www/error/"


#Alias /error/ "/var/www/error/"

<IfModule mod_negotiation.c>
<IfModule mod_include.c>
    <Directory "/var/www/error">
        AllowOverride None
        Options IncludesNoExec
        AddOutputFilter Includes html
        AddHandler type-map var
        Order allow,deny
        Allow from all
        LanguagePriority en es de fr
        ForceLanguagePriority Prefer Fallback
    </Directory>


Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.
