Adding a parameter to the url for all pages
Hi,
I've a custom application that runs on a set number of machines. The
application consists of a custom browser (based on xulrunner and eclipse
swt Browser class) and a tapestry application. Each machine on which the
app runs has a unique ID. Currently, when users use the application,
their information is stored in a standard tapestry visit object.
However, I'm not a huge fan of the http session, and, given my
environment, I could do away with it entirely by simply altering each
submitted URL in the custom browser to include the machine id, and keep
any session-based variables in the database.
This is simple to do via a listener in the Browser. However, I'm not
sure if this is possible on the tapestry side. Basically, each url would
be modifed from http://localhost:8080/app/myPage.sdirect to
http://localhost:8080/app/myPage.sdirect?machineId=4
or http://localhost:8080/app/myOtherPage.sdirect?sp=1
to http://localhost:8080/app/myOtherPage.sdirect?sp=1&machineId=4
Does this idea make sense? Is there a way to always get a parameter like
this out of the URL (regardless of whether it's a GET or POST?)
I've been messing around with this idea in my app, but I'm running into
problems like
'rewind of form myPage/form expected only 0 form elements, but an
additional id was requested by component myPage/null'
Is this notion I've come up with feasible, or have I been smoking too
much crack again?
Thanks
Denis

Never mind - I just came across an example using the cookie source
hivemind service to accomplish this. This is a much cleaner solution. Thanks

That sounds like a good idea. However, I've been unable to find an
explanation as to how to set a value explicitly in a cookie (I know that
tapestry will implicitly set the session value in a cookie for you to
synchronize the server state with the client using a session id) How do
you get tapestry to store some other value in a cookie, and is there a
way to easily access it? I'm using tap 4.1
Thanks

Why don't you just store the unique machine ID in a cookie ?
