问题描述:

I have a really strange behavior while using Mason, for example:

I have an index.html file ( that contains mason tags like <% $var %> hello ).

When I'm browsing to http://bla.com/index.html the variable is translated during compilation.

But there's a strange behavior when I'm browsing to http://bla.com/index.

Though there's no file called index (only index.html) it still loads index.html and the entire code is shown as plain/text including the <% ... %> !!!

What have I configured wrong ?

this is my Apache configuration:

<VirtualHost *:80>

ServerAdmin [email protected]

ServerAlias abc.com www.abc.com

ServerName abc.com

DocumentRoot /var/www/abc.com

DirectoryIndex index.html

<Directory "/var/www/abc.com/">

Options FollowSymLinks MultiViews

AllowOverride All

Order allow,deny

allow from all

</Directory>

SetHandler perl-script

PerlModule HTML::Mason::ApacheHandler

PerlSetVar MasonUseObjectFiles 1

<LocationMatch "(\.html|\.txt|\.pl|\.js)$">

SetHandler perl-script

PerlHandler HTML::Mason::ApacheHandler

</LocationMatch>

<LocationMatch "(\.m(html|txt|pl)|dhandler|autohandler)$">

SetHandler perl-script

PerlHandler Apache::Constants::NOT_FOUND

</LocationMatch>

After a ~year I accidently found the answer, so I wanted to share my findings:

The problem was that Mason(Perl) displaying the code itself of another file on the web instead of providing "404 file not found" and I had no idea how to stop it. e.g: when requesting index it shows the code of index.html

The solution is that in my Apache configuration there was the following:

<Directory "/var/www/my_dir/">
                Options FollowSymLinks MultiViews
                AllowOverride All

                Order allow,deny
                allow from all
        </Directory>

Apparently "MultiViews" is activated through mod_negotiation.c, which cause the site to search for a pattern of the next-best match in-case the file is not found on the server. ( so from www.site.com/index it found index.html )

But because there's no configuration in the Apache to execute /index in Mason ENV ( no file extension ) , it simply displayed the code ...

Funny :) but the solution was to change "Options FollowSymLinks MultiViews" to "Options FollowSymLinks -MultiViews" and not using the MultiViews.

Found this solution while seen the following response headers:

Content-Location    index.html
Vary    negotiate

The "MultiViews" doesn't have any meaning to me, as it was a copy-paste from a 5 years ago that I simply carried from one web-server to another :)

Thanks, Ricky.

Why the webserver automagically

  1. translates index into index.html
  2. still insists on treat it specially (it apparently don't feed it into the PerlHandler as it should) I honestly don't know (perhaps the answer is elsewhere in your configuration).

However, you could as a work around try to add 'index' (or perhaps rather'^index') to the regex that defined what files should be dispached to HTML::Mason::ApacheHandler. I do admit it is a bit ugly though.

Am I correct that once you load the index page and get that verbatim code displayed, once you check out the page info, the encoding is literally plain/text? Perhaps you need to configure some mime settings to ensure that files without suffixes (files not ending with .html etc) are not sent to the remote browser at all, not even as plain/text?
