url question

Recommended Posts

i am trying to understand, how a site like ebay can display content and be case insensitive?
for example:
 

The original url:

http://www.ebay.co.uk/itm/Toshiba-Satellite-C50-AMD-E-Series-1-4GHz-Dual-Core-15-6-Inch-500GB-2GB-Laptop/151458954958

the above works fine and go to the intended page.

user editing the browser url into lowercase :

http://www.ebay.co.uk/itm/toshiba-satellite-c50-amd-e-series-1-4ghz-dual-core-15-6-inch-500gb-2GB-laptop/151458954958

random uppercase and lowercase.

http://www.ebay.co.uk/itm/toshiba-sateLLite-c50-aMd-e-sERIes-1-4ghz-dual-core-15-6-inch-500gb-2GB-laptop/151458954958

both the urls above also work fine and go to the intended page.

 

How can such a thing can work? it is supposed to throw an error such as page not found and the like?

any thoughts welcome.

Everything in a url is case sensitive, browsers will lower the domains though.

So if is a path/folder/file should always do them proper case.

 

What you see there is not a real location but added into the url for seo purposes, as requinix said they probably just use the id.

 

Could be a fancy rewrite rule and the url could look something like this

http://www.ebay.co.uk/?itm=toshiba-satellite-c50-amd-e-series-1-4ghz-dual-core-15-6-inch-500gb-2GB-laptop&id=151458954958

The parameters would be able to be uppercased for display and lowercased for usage.

 

Edit:

Yes this works the same

But I believe Requinix is correct and they are going by the ID at the end.

http://www.ebay.co.uk/itm/some-crap-here/151458954958

loads the same content as the original.

People create uppercase or mix case URLs mainly for branding or SEO purpose.Sometimes they  do this for better readability.Generally it should throw exceptions while user request with URLs not matching the case. But this is avoided by adding some rules in either in .htaccess file or using RewriteMap in httpd.conf^.Second one is less complex and works faster.
