“Our strategy for Webmaster Tools is to improve the web interface and provide important, actionable, and useful information. Our changes are designed to improve the experience for all of our users, including power users. For example, we made changes to have crawl errors going back 90 days and to show the full aggregate count of URL errors instead of just the previous 100,000 cap. Power users can still access the firehose of data through our original GData API. One of the improvements we made is to now display the full count of URL errors, and that should help give more accurate data to larger sites. For example, previously if one site has over 35 million Not Found errors, that number would have been capped and shown as 100,000 errors. Now, that site can see the new number and even see where the increase happened in the historical data.

This won’t work if somebody types in a bad URL, but as a practical matter we’re most interested in trapping errors caused by inbound links to deleted pages. By using wildcards, it’s easy enough to rewrite all your deleted URLs to the custom 404 page. When trapping errors, we silently rewrite the URL to avoid returning a redirect. Here’s sample rewrite code for the httpd.ini configuration file: … [Read more...] about URL Rewriting & Custom Error Pages In ASP.NET 2.0
