URL coding strategies
Hello, I am mounting my URLs so I can list product items like so: http://www.mysite.com/item/id/0 http://www.mysite.com/item/id/1 and so on...then I user this id param to fetch the data from the database. I am not accesing this page directly. I have another page where the items are fully listed (the item's title, description, price, etc) and when the user click on each item, they are redirected to this /item/id page. Is there a way to avoid exposing the item's id, but send it behind the scenes to the next page, so I would have something like: http://www.mysite.com/item/ITEM_TITLE eg. http://www.mysite.com/item/Ford-Ranger-Model-2005 In other words, I'm still using the item's id to fetch it from the database, but the URL shows an SEO friendly version.

Re: URL coding strategies
Hi Henrique, are you using a custom WebRequestCodingStrategy implementation? This class should let you encode visible URL as you prefer.

Re: URL coding strategies
There are two ways to achieve what you are looking for: 1) store a stable, unique textual identifier per product (e.g. Ford-Ranger-Model-2005), and lookup the product from this identifier 2) store a textual identifier - ID mapping in your session and do the lookup when the page is accessed; of course this mapping needs to be created at some point in time so the product page can lookup the proper product ID. Option (2) is rather clumsy as it requires a session for a url that looks stateless/bookmarkable. Also, you cannot get around the fact that you need to be able to identify the product somehow. I'd suggest you take a close look at option (1). In general sending it behind the scenes is impossible in the way you are thinking about it. How would you handle the case that the user bookmarks said item-url, and instead of going to your list page goes to the product page directly? That way the only contextual information you have is what is in the url. Good luck.

Re: URL coding strategies
Hey Bas, you're right, I hadn't thought of it that way. In option 1, how would I go about using a unique textual identifier? Say there are 2 items with the name Ford Ranger Model 2005 but each one is posted by different users, the URL would still be: http://www.mysite.com/item/Ford-Ranger-Model-2005 ..since no reference is made to the user, just to the item itself. Is there a workaround this issue or do I need to make some kind of reference to difference among items with the same title? http://www.mysite.com/item/1-Ford-Ranger-Model-2005 http://www.mysite.com/item/2-Ford-Ranger-Model-2005 http://www.mysite.com/item/3-Ford-Ranger-Model-2005 Thanks. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: URL coding strategies
Well, look at it this way: when the user enters your application without any known state (session or other), how can you differentiate? Only by what you know/get from the url. So yes, if the name itself is not enough input to make a textual identifier unique, you'll have to include more information in the identifier.

Re: URL coding strategies
You cannot have a seo-friendly url _and_ pass objects. If you want to pass an object to another page (say a Product), then you need to create a constructor on the target page which accepts a Product or an IModelProduct. You can then call setResponsePage( new TargetPage( product ) ); The upside is that you only query the database once for the product, but the url is not seo-friendly. vp143 wrote: Hi there, I have a question about URL coding strategies I have decided to use IndexedParamUrlCodingStrategy for friendly URL's.
