Note that requiring cookies might prevent the crawler from indexing
your pages.
This is further discussed here:
http://www.searchengineguide.com/whalen/2004/0210_jw1.html and
http://www.optimizekit.com/kb/categories/Do's-and-Dont's/
Major points here: crawlers will absolutely refuse to index pages with
cookies or jsessionids.
If I had a choice between decent back support versus getting indexed
by Google, I'd choose the latter :) Hopefully we can do both.
I take your point seriously, but as stated before, we just can't do
that. There are break out's though, the easiest one to do url rewriting.
This is from the site you sent a link to above:

One way to circumvent this difficulty is to create static versions of
your site's dynamic pages for search engines to crawl. Unfortunately,
duplicating your pages is a huge amount of extra work and a constant
maintenance chore, plus the resulting pages are never quite up-to-date —
all the headaches dynamic pages were designed to eliminate. A far better
strategy is to follow the lead of Amazon and rewrite your dynamic URLs
in a syntax that search engines will gladly crawl.
*URLs that look like this: *
amazon.com/store?shop=cd&sku= B00004WFIZ&ref=p_ir_m&sessionID=
107-6571839-6268523
*/become:/*
amazon.com/exec/obidos/ASIN/ref= B00004WFIZ/ref=pd_ir_m/107-6571839-6268523

You could do either the rewrite (the easiest) or create static pages
from your dynamic content now.
Another thing I'd like to note here is that Wicket doesn't force you to
use cookies. Wicket does all the encoding for you, where's when working
with e.g. plain JSP's or model 2 frameworks, it is a common thing to
forget to encode all links. And if you forget it, it means your browser
has to fall back on cookies, or that - in case you configured your
servlet engine to not use cookies - it fails. I've seen this go wrong
(developers forgetting it) in /every/ webapplication I know of, allways
resulting in complaints that the webapp didn't work for some people
(that is the people that turned of cookies) after it was put in production.

Nope, we do need a session for everything except a trivial page (and
from the framework to figure out whether the page is 'trivial' that
would involve some major hacking). EVERYTHING that can trigger a
'postback', be it forms, links or whatever, needs that page to be in
the session.
It might be a feature request for our next version (1.2 that is) when
we tackle the whole stateless page thing (if we ever tackle that
succesfully, as currently the disadvantages seem to be greater than
the very few advantages it would get you... but that's another
discussion for some other time). But for 1.0.1/ 1.1, we can't change it.

First, I like the new setPageAlias() functionality :)
I still don't understand however why one needs to store the Page
component ID on the session (at least for bookmarkable pages the
first time they are hit). Also, Eelco previously mentioned that
jsessionid is only showing up because we're creating a session. My
point is, we *shouldn't* be creating a session for bookmarkable
pages unless for example the page contains a form, and someone
submits it. We should be creating session on-demand, not right away.
Maybe once I understand more about why we need path=X, this will
make more sense.
Thanks,
