Spell checking universal resource locator (URL) by comparing the URL against a cache containing entries relating incorrect URLs submitted by users to corresponding correct URLs

摘要

A cache, storing misspelled or otherwise incorrect network addresses from a plurality of users and associated correct network addresses, is maintained at a proxy server or internet service provider. Addresses received from all users are checked against the cache to correct any misspellings or other situations in which the network address might be incorrect. The cache is periodically pruned of entries which aren't frequently used. The collective experience of a group of users can thus be utilized to correct a network address submitted by a user who has never visited a particular network address before.
