In google webmaster tools i seem to be getting of 503 pages and other errors The website is old. Mainly from old url's that don't exist anymore.
For example page.com/meubels?page=75&%24Version=1&%24Path=%2F => returns "Disallowed Key Characters."
Another url error is the following: page.com/brands/brand%3Fpage=1?page=1 => returns "The URI you submitted has disallowed characters."

Is it possible to have a 301 redirect to such url's through htaccess or any other way to redirect visitor's to the correct pages in staid of having them stuck on old url's with error pages.
