R – Will a Lisp dialect that works with Apache Tomcat

apacheclojurelisptomcat

Is there an application server like Apache Tomcat that I can use with a Lisp like web language?

I've been playing a little bit with Arc/Anarki and Clojure lately. But what I really miss is something like mod_arc or mod_clojure for Apache. What I really miss is good Apache integration for a Lispy web language.

Both Arc and Clojure use their own built in webserver that you launch within your code. I want all the functionality, resiliency and scalability that Apache httpd gives me. Is anyone working on an Apache module for Arc or Clojure? Is there another Lisp like language that I can use with Apache?

I come from a background in PHP and Perl. But also have lots of experience in C and /bin/sh. Since when I started writing web apps I was using cgi-bin and stdin to C binaries.

You can set up a Clojure/Java HTTP server (Jetty, etc.) running on some port, then use Apache's mod_proxy to forward certain requests from Apache to Clojure on that port. Something like this in your Apache configs:

    ProxyPass /static !
    ProxyPass /cgi-bin !
    ProxyPass / http://localhost:8080/
    ProxyPassReverse / http://localhost:8080/

So Apache will send every request to your Clojure app on port 8080 except requests to things in /static and /cgi-bin, which Apache will handle itself.

Javascript – Is ECMAScript really a dialect of Lisp

Brendan Eich wanted to do a Scheme-like language for Netscape, but reality intervened and he ended up having to make do with something that looked vaguely like C and Java for "normal" people, but which worked like a functional language.

Personally I think it's an unnecessary stretch to call ECMAScript "Lisp", but to each his own. The key thing about a real Lisp seems like the characteristic that data structure notation and code notation are the same, and that's not true about ECMAScript (or Ruby or Python or any other dynamic functional language that's not Lisp).

Caveat: I have no Lisp credentials :-)

Javascript – Running Node.js in apache

Hosting a nodejs site through apache can be organized with apache proxy module.

It's better to start nodejs server on localhost with default port 1337

Enable proxy with a command:

sudo a2enmod proxy proxy_http

Do not enable proxying with ProxyRequests until you have secured your server. Open proxy servers are dangerous both to your network and to the Internet at large. Setting ProxyRequests to Off does not disable use of the ProxyPass directive.

Configure /etc/apche2/sites-availables with

<VirtualHost *:80>
    ServerAdmin admin@site.com
    ServerName site.com
    ServerAlias www.site.com 

    ProxyRequests off

    <Proxy *>
        Order deny,allow
        Allow from all
    </Proxy>

    <Location />
        ProxyPass http://localhost:1337/
        ProxyPassReverse http://localhost:1337/
    </Location>
</VirtualHost>

and restart apache2 service.
