>> Parameters for a static file? Or does vignette use .html as an extension for an ISAPI filter?
Yes, it could be any extension. >> So the 1674 part is the only part of all that which is actually useful eh? :) No, all the parameters are usefull (0,1674,P249,00), especially P249 and 00. I re-explain : 1674 is the ID of the template to execute, P249 is the OID to pass to the template (it could be a list of parameters) and 00 are the capabilities of the browser. If the template display an article, it will generate one static html file per article (one per OID) for each browser capabilities (if there is any difference for each browser in the output). Ex. : - 0,1674,P249,00.html, - 0,1674,P249,FF.html, - 0,1674,P250,00.html, - 0,1674,P251,00.html... If the 0,1674,P249,00.html file already exists in the cache directory, it is directly served by the web server without any dynamic processing. If you can also use URL parameters (0,1674,P249,00.html?var1=toto&var2=titi), but if the template is cached, they won't be taken into account (ignored by the web server), that's why you can't put P249 as a normal URL parameter, it has to be in the file name for the caching system to work. >> Try giving someone a url like that verbally -- ever worked >> technical support where you had to give someone a url >> over the phone so they could download a driver? We've designed, developped and run several high-end B2C web sites and we never had to encounter this kind of problem. All our applications have automatic error trapping system and nicely structured navigation system. They also have "friendly URLs". ;) In my previous mail, I was not saying, that Vignette naming was a great one. I was just explaining that it was linked to the way their caching system works. I definitely agree : if you can have "friendly URL", you should keep them friendly (and avoiding UUID is already one way to do it). "Why making thing complex, if you can make them simple" is a CF motto... ;) Benoit Hediard -----Message d'origine----- De : S.

Yes, Tapestry does this... or it can if you need/want it to -- it's not a necessity.

If you say so, but I'm fairly certain Vignette doesn't do anything with that url than I can't do with a 4 or 5 digit number. As a matter of fact, I'd be willing to bet that much of this is already done by Tapestry -- the caching that is... > So OK, the URL aren't very URL friendly, but I don't think > that URL have to be "friendly". User never look at the > URLs, only web developers do.. ;) Did you get a chance to read my first message on this thread? Real non-developer people frequently look at those url's, and often have to give them to people over the phone, which is a major pain... Sounds like you've never worked in a tech-support queue -- as just one example of an instance in which non-developer people must frequently pass a url verbally. I worked in Hewlett Packard's corporate tech-support queue for a year ( was actually my first technical job ), and the fact that their corporate website where people had to get drivers was a nightmare to navigate was a _huge_ problem. They didn't use Vignette, but something like what you see below was a _common_ occurrance on the phone. And this was even talking mostly to IT and MIS department techs whos job it was to repair our workstations. > Try giving someone a url like that verbally -- ever worked > technical support where you had to give someone a url > over the phone so they could download a driver?

Generally speaking I think it's foolish to assume that non-technical people will never do or need to do something when it regards your software -- especially when it's something as necessary and readily available as a URL. Users will do what they need to in order to accomplish anything that's really important ( in the case of the tech-support person, it's their job to make sure that people can get the drivers they need, etc. ) but we don't need to go out of our way to make things complicated for them.
