Fetch Prototype library via Google DNS?
How can I configure Tapestry to fetch the Javascript Prototype library from
the http://code.google.com/apis/libraries/devguide.html#prototype Google
DNS server ?
Cheers!
Stephan

You can configure the Tapestry Scriptaculous Path to get prototype library in
google.
I think that will do the trick. :)

That is exactly what drove the changes in JavaScript aggregation for
5.2. What's you'll see now is a request for a core.js (the core
JavaScript stack: prototype, etc.) plus additional requests for each
"non-stack" JS file (if any).
In both 5.1 and 5.2, per-page JavaScript initialization is in a <script> tag.

I'm not sure this always makes sense to do. One of our applications
has a couple wizard-like interfaces where you answer a few items and
move through until the end. Each page had a tiny little bit of
page-specific JavaScript to be delivered in addition to the common
JavaScript (Prototype, Tapestry, etc). If Tapestry is always
re-packaging all of the JavaScript, plus the small page-specific
JavaScript, into a single JavaScript file, isn't this more wasteful?
The browser can't cache Prototype, but has to re-download it each
time, right?
Thanks,
mrg

Depends on the patch, eh? :) But in all seriousness, like the majority
of my other "enhancements", they are not good/generalized enough for
general use. Probably not worth doing it for 5.1 anymore. Now things
have changed sufficiently in 5.2 that it may require a different take.
Perhaps I'll make an effort for a patch once I get to it unless
somebody else gets there first.

And that advantage cannot be discounted for. Almost at 60KB, nothing
else comes close to the size of the Prototype stack in a typical,
reasonably designed web application if it's not primarily serving the
heavy media types. Sure it's cached and all, but a small website
relies primarily on new users to find the site and that 60KB may be
enough of a turn off because of general lack of responsiveness.
Using a CDN for loading heavy elements is free from web site's
perspective and it can be done with Tapestry, but it just makes it
needlessly difficult to do so.

That article doesn't take into account the things that Tapestry does for you:
- Combines prototype.js with other JS files to form a single JS file
(this is done on-the-fly)
- GZIp compression of the virtual asset
- Far future expires header for the virtual asset
- A couple of bug fixes in the Tapestry version
... and, perhaps in 5.3, on-the-fly minimization of the virtual asset.
The only real advantage to fetching from Google is that the browser
may fetch more of the JS files in parallel, since the fetching is
across multiple hosts.

Isn't that an oxymoron? Setting the 'tapestry.scriptaculous' to fetch
prototype - or am I not seeing something? :)
I already had a look at the 'tapestry.scriptaculous' and
'tapestry.scriptaculous.path' configuration variable and it seems it only
works for resources out of a JAR - when I played with it somewhere in the
stacktrace it said LocalAsset or something similar...

Why do you want this?
In a production application, Prototype will be bundled with the
necessary Scriptaculous and Tapestry libraries into a single "virtual"
asset.
