Friendly URLs - how to avoid duplicate pages when no parameter is given in the URL

Hello Guys,

I have a website where the users can change the city and the currency

This will give them the price of the service in the chosen city and the price will be converted in the chosen currency

The typical URL scheme is http://localhost/language/city/currency/ for example:



The default city is set to "Paris" and the default currency is set to "EUR", which implies that loading the 3 following URLs will have exactly the same content:



I guess it's not SEO optimal to have duplicate pages

It's the first time I am confronted to this situation and I have no clue how to remove those duplicates

Should I use modx->sendRedirect or sendForward?
Should I add the missing parameters to the URL directly in .htaccess?

Maybe should I just move the city and currency parameters to session variables or cookies ?

Thank you for the help [ed. note: radoslav last edited this post 9 years, 9 months ago.]

One solution is to make the alternate URLs Weblinks or Symlinks, but it is kind of wasteful to have so many different resources in the DB when you actually only need one.

I think I would post the form to itself and have a snippet on that page that produces the results after getting the three $_POST variables. That way the whole project is a single resource and one snippet.

Another way to go would be to use JavaScript on the page to produce the results without a page reload.

Hi BobRay and thanks for the help,

Excuse me I don't understand your advice, but surely my question was also not clear

My problem is simply that the start page url is http://localhost/en/ but then the user can choose a city and currency which implies the url will be http://localhost/en/city/currency/

Tf the city and currency paramters are not set in the url, I programmed a default city and currency (Paris and EUR) that apply to http://localhost/en/, this means that http://localhost/en/ and http://localhost/en/Paris/EUR/ are strictly duplicates

In other words, how to add url parameters to the start page

I just would like to have http://localhost/en/Paris/EUR/ as start page (instead of http://localhost/en/ currently)

Thank you

Really, the easiest thing is to put a canonical tag in the head section of the template containing the preferred URL. That will avoid any SEO penalty for duplicate content.

Thank you BobRay !
