How to use Plack::Middleware::Static

vhein79 has asked for the wisdom of the Perl Monks concerning the following question:

Hi!

I run a website, changing now from FCGI to PSGI using Plack as server. The behaviour should be the same as with the old Apache website, (which I configured with .htaccess files for each directory) so I want to use js when it is needed, and show it as text/plain when someone clicks such a non binary file in my download directory.

I don't want to use dancer etc now, because I had to make big changes to the website then (FCGI and PSGI are quite similar to use). I tested a bit and the behaviour seems to be version dependent (on Windows it works, on CentOS not), but I want a safe way using different Plack::MIME instances for different directories.

What I have now uses the same Plack::MIME instance and doesn't work correctly when I include .html, .css etc there:

use Plack::Builder;
use Plack::MIME;

# normal behaviour  /html/
# special behaviour /html/downloads/

for my $expr (
         ".c", ".cpp",".csv", ".dat", ".dpl"
       , ".gp", ".h", ".hpp", ".ini"
       , ".java", "makefile", ".m", ".mac"
       , ".pl", ".pm", ".pod", ".py"
       , "README", ".sch", ".sh", ".txt") {
  Plack::MIME->add_type($expr => 'text/plain');
} 
 
builder {
  enable 'Plack::Middleware::Static',
    path => qr{/html/}, root => '.';

  # normal behaviour:
  # needs a new content_type instance! how doing this?
  # enable 'Plack::Middleware::Static',
  #   path => qr{^/html/(?!downloads).*\.
  #              (css|gif|jpg|js|pdf|png)$}, root => '.'; 
      
  mount "/" => $app1;
  mount "/imggenerator.pl" => $app2;
};
[download]

I could treat every single file in my $app1, but I think configuring that with Plack should be possible.

Thank you for the really fast answer! This works: use Plack::Builder; use Plack::MIME; for my $expr ( ".c", ".cpp", ".css", ".csv", ".dat", ".dpl" , ".gp", ".h", ".hpp", ".html", ".ini" , ".java", ".js", "makefile", "Makefile", ".m", ".mac" , ".pl", ".pm", ".pod", ".py", "README", ".sch", ".sh", ".txt") { Plack::MIME->add_type($expr => 'text/plain'); } builder { enable 'Plack::Middleware::Static', path => qr{^/html/downloads/}, root => '.'; enable 'Plack::Middleware::Static', path => qr{^/html/(?!downloads).*\.(css\|gif\|jpg\|js\|pdf\|png)$}, root => '.', content_type => sub { Plack::MIME->mime_type($_[0]); }; mount "/" => $app1; mount "/imggenerator.pl" => $app2; }; [download] But I'm far from really understanding it and there still is one issue: .html in downloads are still treated as html files, not as plain text.

Per default, `Plack::Middleware::Static` will serve your files depending on their extension by using `Plack::MIME`. So I suggest that you just drop your own invocation of `Plack::MIME` for the "normal" behaviour and override it for your download directory like this: `content_type => sub { 'text/plain' }` Edited to add: After a glance at the code, you can also provide the content type directly: `content_type => 'text/plain'`	[reply] [d/l] [select]

Have you confirmed that the server is actually sending `Content-Type: text/plain`? I know at least some browsers once would interpret `text/plain` as `text/html` if the contents "look like" HTML and I do not know if modern browsers still do that.	[reply]
