How to trap and redirect [callbacks]

[superjacent]

I thought I had a handle on re-directs but I can't get my head around this one. I'm going around in circles.

Checking my recent log entries at my site, it reveals that I'm getting a lot of 'Page Not Found' errors and the offending URL's are similar to this:-

http://example.com/taxonomy/term/drupal/?_menu[callbacks][callback]=http://www.example.com/folder/filename.txt?

Everything from the "?_menu" on is crap and false. How do I trap for this and redirect to another page. This is what I've tried so far but doesn't work (and then a heap of variations):-

RewriteCond %{QUERY_STRING} ^\?_menu\[callbacks\]
RewriteRule ^$ http://example.com/node/89? [R=301, L]

Any help appreciated.

The question mark that demarcates the query string from the URL will appear in neither the %{QUERY_STRING} variable nor the URL-path examined by RewriteRule. Remove the question mark from your pattern.

Thanks for advice.

Removing the question mark has at least stopped the internal server errors occurring.

Writing these lines doesn't appear to work, I still get a 'page not found' error and the url in the address bar hasn't changed.

RewriteCond %{QUERY_STRING} ^_menu\[callbacks\]
RewriteRule ^$ http://example.com/node/89? [R=301, L]

You may need to represent the "[" and "]" characters as URL-encoded entities, such as "\%5b" and "\%5d" in your pattern -- I'm not sure, but that's a possible cause.

Hate to say this but that's not working either. Even reducing the criteria to this, doesn't work.

RewriteCond %{QUERY_STRING} ^_menu
RewriteRule ^$ http://example.com/node/89? [R=301,L]

With the above, I'm getting Internal Server Errors and yet last night when checking (removing the question mark as advised in previous message) I was at least getting 'page not found' errors.

What is in your server error log file?
(You may need to add

Options +FollowSymLinks

ahead of your code if you see a message mentioning it in the error log)

Where is this .htaccess code located? (should be in http://example.com/taxonomy/term/drupal/.htaccess)

It does follow symlinks in the .htaccess file.

The .htaccess file is at the root, where index.php file is.

There is no sub-directory /taxonomy/...

I'm in the process of seeking advice from my host re - the server logs.

My application is Drupal a Content Management System. I've got clean url's enabled (I believe it's also known as static url's).
