I have a table containing URLs. I want to be able to look up an URL very
fast, so I used an nvarchar to store the URL, and put an index on it
(maybe naive).

Anyway, I bump into:
"The index entry of length 911 bytes for the index 'UQ__URL__1367E606'
exceeds the maximum length of 900 bytes."

What's the best way to handle this? I want to do the look up fast. The
only thing I could think up was adding an extra column containing a digest
for the URL, and look up all URLs with the same digest, *and* having the
same value (which could give either 1 or 0 results).

I am new to MS SQL, so I might describe a silly solution, basically I want
to look up URLs to ID the fastest way possible.
