Yes, I have to look deeper (as I'm not a Ruby specialist)

Yes, but I use NGinx and I feel ok with it. Maybe I should try that,
mainly for the challenge.

If SwitchPipe's doing that, then either the app is not responding
within a certain number of seconds, and SwitchPipe is then forcing a
restart (I think this is in the settings) OR the app is simply not
responding or SwitchPipe cannot connect to it. I have not come across
a Rails application, at least, that takes more than 5 or 6 seconds to

Oupsssss !

Thanks for your help, it was simply a path problem : the good one
should be path: /var/www/nginx-default/rorprot rack
Now it works for a little useless app. I've tried to set it for
another one, but switchpipe kill and restart indefinitely the thin
process.
I'll have to look futher deep before asking for some help.

Start from something simpler, and work your way up. That should
highlight where the problem is.

Also, you need to make sure that wherever "thin" is located is within
your path. SwitchPipe will go to /var/www/nginx-default/rorprot ack and
then run:

thin --socket /tmp/switchpipe-[[RANDOMISH NUMBER HERE]].sock -u www-

I try since several hours to make Switchpipe to launch Thin instance
via socket to deliver service for a rails app.
Here is the switchpipe app config file :
---
type: thin
socket_type: unix
user: www-data
group: www-data
path: /var/www/nginx-default/rorprot ack
max_instances: 3
timeout: 9

Or both. Even though .htaccess will be in file cache, it'll still add
time, and being prepared to deal with regular expressions will keep
rewrites a little slower too. I will try and update the documentation
with your example for those who are interested :) (Once I play with it
myself, of course - I have something your tips might suit deployed

This is a FreeBSD specific init script I'm afraid. Linux works in
quite a different way to the rc.d system of FreeBSD. At least that's
as I understand it.

As shell scripting is pretty generic, it may be possible to turn one
or the other into a generic script by testing which platform it is

It just seems simpler than using rewrite rules (to me).

Testing on FreeBSD 7.0 64 bit platform, Xeon 2.33 Mhz dual core, this
arrangement only seems to add about 1ms overhead using Switchpipe as
opposed to just sending the request to a mongrel instance alone.

Using rewrite with .htaccess files uses about twice that. Don't know

Just a question..

Am I going to need to have an init script for BSD and one for Linux?
Or are the additions you've made pretty generic in terms of rc.d init
scripts?

That is a really cool example you've given; thanks! I didn't realize
you could do that with ProxyPass.

Cheers,

Excellent work, and thanks for the information! I'm going away for two
days tomorrow but will get this sorted out at the weekend. I'm also in
the middle of migrating SwitchPipe to Github so that contributions
will become a lot easier :)

Prevent proxying of static assets

g...@gpdnet.co.uk (Gary Doades) — Tue, 15 Apr 2008 13:48:26 UT

If you can't use rewite rules for some reason, proxying works just
fine. The setup instructions currently state that getting apache to
serve static files is a problem in this case. However, the following
example will prevent proxying of the static assets for a standard
rails application.

Inside a VirtualHost perhaps.....

If anyone is interested I have managed to get switchpipe (1.04)
working on FreeBSD 6.2/7.0

During setup the only thing that doesn't work according to the
instructions is the automatic installation of the required gems
because FreeBSD doesn't have a sudo command by default. You can either
intall sudo from ports or just install the gems manually first. The

pcoo...@gmail.com (Peter Cooper) — Mon, 14 Apr 2008 00:58:21 UT

Definitely keep me / us informed of how this goes :)

Just so you know, another thing I have on the cards is to rewrite all
of SwitchPipe into Python or Perl once the feature set is reasonably
solid. This won't radically improve performance because most of the
latency is in the networking and the process management, but should

Yeah, I would definitely agree that the 301 approach makes more sense
long term. Also, I'm glad to bring things like this up, since if I
roll SwitchPipe out in my production environment, it will definitely
make life easier for me.
