{Internal Process User Agents - Do Not Log}

{* Do not redirect 404s from the user agents listed here.}
{* Do not capture 404 URLs.}
{* Strings are case insensitive.}
{* One string per line.}
{* If the string appears anywhere within the user agent string then it's a match.}

{This is best for internal processes that don't need to be redirected when the slug structure changes. Search engine user agents should not go here so that they will be redirected when the slug structure changes.}

{External User Agents - Do Not Log}

{* 404s are still redirected when possible.}
{* Do not capture 404 URLs.}
{* Strings are case insensitive.}
{* One string per line.}
{* If the string appears anywhere within the user agent string then it's a match.}

{This is best for search engine bots that do need to be redirected when the slug structure changes. Use one line per user agent. If the text is found anywhere in the user agent string then it applies.}
