Apache 2.4 – Set Headers for Error Pages in .htaccess

.htaccessapache-2.4http-headers

I am setting some headers using .htaccess for a web page, f. e.:

<IfModule mod_headers.c>
Header set Strict-Transport-Security "max-age=31536000; includeSubDomains"
</IfModule>

This works fine for usual page access, but the headers are not used on error pages like 404 Not Found and 403 Forbidden.

Is there a way to set Headers for error pages using .htaccess?

Header set Strict-Transport-Security "max-age=31536000; includeSubDomains"

For non-200 OK responses you need to use the always condition:

Header always set Strict-Transport-Security "max-age=31536000; includeSubDomains"

Note that always (as opposed to onsuccess - the default) refers to the internal table of HTTP response headers, it doesn't necessarily mean that it is always set.

Python – You don’t have permission to access /index.py on this server

Have you checked your error log? It's the first place to look.

I think your AddHandler is incorrect. The documentation says it is used like so:

Syntax: AddHandler handler-name extension [extension] ...

application/x-httpd-cgi isn't a handler, it's a MIME type.

You probably need ExecCGI on (see the docs). This is usually enabled for /cgi-bin/ but if your file's not in there you'll need something like this in your .htaccess

Options +ExecCGI
AddHandler cgi-script .py

This relies on your server allowing .htaccess files. See the AllowOverride documentation.

You don't need RewriteEngine On and DirectoryIndex just sets the file returned when you hit the containing directory (i.e., /python/) with no filename.

This solution just enables execution of .py scripts using mod_cgi. Other solutions which have suggested mod_python will also work but this is more complex and embeds a Python interpreter in the Apache processes. This isn't needed for straight execution using the system Python interpreter.

Send 404 error code on forbidden directories

not a straight answer, but if you have php [ or other server side include scripting ] installed - you can use:

ErrorDocument 403 /404.php

and in 404.php have:

<?php
  header("HTTP/1.0 404 Not Found");
  //...
