[users@httpd] HTML compression module?
Hi,
I found a site that lets you paste (X)HTML or CSS into a textarea and submit
it to a script that strips out newlines and other stuff that is not strictly
necessary for correct parsing. This effectively "compresses" the stuff - I
lopped 40% off of my css file. It's at
http://www.peterbe.com/plog/blogitem-040406-1/compressor - I'm sure there's
lots of other sites offering this type of thing. I just Googled upon this
one first.
Anyhow, does anyone know of a module for Apache that does this to content as
it leaves the server? It's an interesting alternative, or perhaps additive,
to gzip'ping the content, for browsers that don't support that (which, btw,
does anyone know which versions of IE support compression?) I'd do it
on-disk instead of live, but my setup consists of PHP programs feeding
Smarty data from themselves and textfiles, so the HTML is too spread out to
make that a convenient and attractive solution.
I'm thinking the overhead of the server doing this might outweigh or hardly
make a dent in the bandwidth savings enough to make this feasible, but it's
a worth a shot. I might even write the module myself if there isn't already
one and it proves to be worthwhile enough. What do you guys think?
Thanks,
Joey

Is a GPL'ed whitespace compressor written for my html editor of choice
(HTML-Kit), looks like it is written in its native scripting language
(HKScript), but look at it as a pseudo code implementation and re-write in
your language of choice and write a module wrapper around it.

Actually, unless you're dying to ;) , I think I'll give it a try. Then I
can say I have my own code helping serve up my content. ;)
Anyway, I use whitespace liberally, so my savings may amount to more than
the average person's, but I still don't think I'll get much. I don't even
have a heavy-traffic site or pay by the amount of bandwidth I use, so it's
not even real important to me, just an interesting idea I want to see work.

Cheers,
Joey

I guess you have lots of whitespace:-)

Yes, but it's part of something bigger, and not published.

Actually it'll gain a lot less than you'd think, because once you've
stripped down the whitespace, the compression you get by gzipping it
will be correspondingly less.
As an alternative - yes, it's a possibility.

Actually the server overhead could be pretty negligible: certainly less
than gzipping it.

If you take a simplistic approach (and don't mind screwing up <PRE>), the
module would be maybe an hours work. You could perhaps take mod_txt as a
startingpoint for manipulation like this.
Alternatively, grease my palm and I'll write it for you:-)
