Mod_ruby + mod_deflate

Ruby
1

Hello!

I’m running an application written in Ruby using mod_ruby wtih Apache,
the application is pretty fast and responsive but output compression
via mod_deflate may help to bring even more speed and save bandwidth.

The problem is that it appears to be very hard to make mod_ruby and
mod_deflate to play well together.

This is my simple mod_deflate configuration:

AddOutputFilterByType DEFLATE text/html text/plain text/xml

Indeed I’m generating text/html from mod_ruby.

Still it does not compress at all, while in the same box
output from PHP scripts are compressed without problems.

I tried to load the deflate module as last module but still
it does not work.

Somebody aware of the black magic required to make this working?

Thank you very much for your help,
Salvatore

That’s fine, but apache may not know that. First, get rid of the
IfModule lines, they just serve to make debugging problems like this
harder (because it could be that you don’t have the module loaded).
And then, check how you’re telling apache to pass the request on to
mod_ruby. If it’s with AddType, replace that with AddHandler, and use
AddType to tell apache that the mime-type of your handler is
text/html. If that doesn’t help, reply (to me directly too please, I
find this list hard to keep up with) with your apache config and I’ll
see if I can reproduce the issue.

Ok Thanks, actually adding the line:

AddType text/html .rhtml

to my existing configuration solved the issue, now the
pages are compressed correctly.

The only virtual problem with this is that if I want
to generate images or other content it’s not worth
to compress from Ruby this may be compressed anyway
but I solved the issue using .rb files to generate
this kind of content while using .rhtml files only when
the output is really HTML, so everything is fine.

Thanks again,
Cheers,
