RE: [wsrp-wsia] [I#196] Consumer can not force consumer rewriting tobe used for URLs

[Rich Thompson <richt2@us.ibm.com>]

Lets think through the scenario to see where it could break:
 1) The Consumer defines its template in such a manner that Consumer URL 
writing is used 
              [fragment => 
...&wsrp-navigationalState={wsrp-navigationalState}]
 2) Producer stores this template in its markup for embedded javascript to 
use 
              [fragment => 
...&wsrp-navigationalState={wsrp-navigationalState}]
 3) Consumer finds the embedded template and rewrites it
              [fragment => ...&ns={wsrp-navigationalState}  or 
/ns_{wsrp-navigationalState}/]
 4) JavaScript runs and replaces the Producer supplied values
              [fragment => ...&ns=fooBar  or  /ns_fooBar/]
 5) URL is activated for Consumer processing


To me this looks like it works provided:
  1. Consumer finds/replaces "&wsrp-navigationalState=" and does not touch 
{wsrp-navigationalState} => worth mentioning in the primer to avoid 
Consumer bugs in this area.
  2. Producer never breaks up a template when storing it for client side 
JavaScript use. This would be a dangerous thing to do anyway and therefore 
merits a mention in the primer as well.

I am starting to wonder if we are gathering enough of these types of 
things that we should consider a "Best Practices" document as well. We 
certainly should be using a separate portion of the primer from the 
tutorial until we are ready for splitting in this manner ....

Hi Eilon.

Can you detail on this. I think I do not understand why the approach to
provide ANY tempalte (including the one that results in consumer 
rewriting)
should not work for the javascript code. That would worry me.


Best regards

This could be a great way to test WSRP initially. To the best of my
understanding, though, such a technique would not necessarily be 
applicable
to real-life situations. For example, if a Producer has JavaScript that
executes document.location.href = url; and the Producer takes care to
create a proper JavaScript (which takes into account the provided
templates), then providing the Producer with a dummy template is not
guaranteed to work. (I.e., we rightfully don't demand Producers to support
this hack ;-)

      It is quite easy to supply a default template that results in
      Producer URL
      writing outputting the format for Consumer URL rewriting.

      Topic: user_info
      Class: Minor_Technical
      Raised by: Andre Kramer
      Title: Consumer can not force consumer rewriting to be used for URLs
      Date Added: 18-Dec-2002
      Document Section:   v0.85/9.2
      Description:
      In the 1.0 timeframe, it would be good, for testing and bug work
      arounds,
      to allow the consumer to not supply templates to a producer which
      indicates "doesURLTemplateProcessing", so that consumer URL 
rewriting
      is
      forced to be used. [Spec says consumer MUST supply templates but all
      URL
      templates are nilable or minOccurs="0".]
