.htaccess redirect problem

Sorry, not sure if this is an appropriate forum for my enquiry. But just haven't found siutable category. Here is the problem:
I redirect a big number of files with 301 redirect in .htaccess file.
The redirect line for each file looks like this:

Code: Select all

redirect 301 /old/old.php?id=1 http://www.mysite.com/new.php?id=1

but it redirects me to

Code: Select all

http://www.mysite.com/new.phpold.php?id=1

What should I do? I'm having dozens of highly ranked pages... Need to save my positions. Please help!

I'm no expert on this, but do any of these help?

Thank you Ryan. I didn't think of formulating my google query this way. The solution though was found yesterday and it appears to be very simple. I tryed to remove my redirect rules one after another. So that if originally I had:
redirect 301 /old/ http://www.mysite.com/new.php
redirect 301 /old/old.php?id=1 http://www.mysite.com/new.php?id=1
redirect 301 /old/old.php?id=2 http://www.mysite.com/new.php?id=2
redirect 301 /old/old.php?id=3 http://www.mysite.com/new.php?id=3

and it worked correctly for the base url only (1st redirect)

Now I have simply removed anything after the first line - and it workes fine for all the dynamic urls based on www.mysite.com/new.php

It really troubled me I should admit. Quite a bit of work has been done to achieve our current positions in SERPs and I didn't want to roll back to the old design/structure either.

The other possible question out of this is how to make a rewrite rules with mod_rewrite for the new urls having redirects from the old (non-exsisting) ones. Or in other words:
Task #1 to redirect http requests from the old urls to new ones (accomplished)
Task #2 to make new urls SE friendly (give them a static look)
Would it be ok just to add rewrite rules after 301 redirect rules into the same .htaccess file?

I'm going to bow out on this one, I only use static pages. Sorry!
