htaccess Redirect for dynamic URL's

[cape]

Hi

I need a redirect for ID items from a database. The server has been changed from ASP to PHP, along with a new directory system, and the old ASP addresses no longer exist.

I need to redirect:

http://example.com/Directory/search/dispBusiness.asp?BusID=00000
to
http://example.com/component/option,com_mtree/task,viewlink/link_id,00000/Itemid,32/

where 00000 is a variable ID number.

I've torn my hair out trying everything! Can anyone help with this please?

Thanks

Opsss... sorry you can't redirectmatch a query string

So it must be

RewriteEngine On

RewriteCond %{QUERY_STRING} ^BusID=([0-9]+)$
RewriteRule ^/?Directory/search/dispBusiness\.asp\?BusID=([0-9]+)$ http://example.com/component/option,com_mtree/task,viewlink/link_id,$1/Itemid,32/ [R=301,L]

Thanks for your reply.
I am stil getting the following:

Not Found
The requested URL /Directory/search/dispBusiness.asp was not found on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

Usually when a new .htaccess file is created,or an existing .htaccess file is deleted, however, these changes will not be seen until the htaccess cache is cleared. Depending on the hosting provider you're using this process may take place every hour or two.

The reason that RedirectMatch and the above mod_rewrite code won't work is that query strings are not part of a URL but rather data attached to that URL, to be passed to the resource *at* that URL. Therefore, neither RedirectMatch not RewriteRule can 'see' the query string.

Try:

RewriteEngine on
#
RewriteCond %{QUERY_STRING} ^BusID=([0-9]+)$
RewriteRule ^/?Directory/search/dispBusiness\.as[b]p$[/b] http://example.com/component/option,com_mtree/task,viewlink/link_id[b],%1/[/b]Itemid,32[b]/?[/b] [R=301,L] 

instead.

This assumes that the values of "option," "task," and "ItemID" are fixed values based only on the match with the requested URL, because they cannot be derived as variables from that requested URL. For example, the value of "ItemID" in the new URL will always be "32" because the the originally-requested URL carries only "LinkID" as a variable, and does not explicitly contain any information about the ItemID.
