how to constract absolute URL from relative URL string

Hello all
how can i get absolute URL from relative URL string like "../foo.html"
like like "http://www.mysite.com/stuff/foo.html"

thanks

You will need the base URL as well, like "http://www.mysite.com/stuff/subfolder/". Then just use one of the URL constructors that takes a URL object as the first parameter:

Note that the base URL needs a trailing / if it is a folder, or the "subfolder" part will be considered as a file, and "stuff" will be considered as the current folder.

but what if i have only the site host url like
"www.mysite.com"
and then i have in the links only the relative URl like :
..\..\foo.html
can i somehow construct full uri ?

This code should work

If you don't know the current URL, you can't of course determine the absolute URL of any relative URL. For instance, ../foo.html will have a different absolute URL if found on www.mysite.com (www.mysite.com/foo.html), www.mysite.com/mypath (www.mysite.com/foo.html) or www.mysite.com/mypath/mysubpath (www.mysite.com/mypath/foo.html).

So your first step is: determine the full current URL, or you can't do a single thing. If you don't know the domain, you can actually add any domain and later cut it off again. "localhost" tends to be a good one
