Redirect using query string and output is plain url

I’m trying to make a redirect rule to take a specific url and query string and redirect to a URL.
Incoming URL www.example.com/content?content=1234
Output www.example.com/someurl/

Then

Incoming URL www.example.com/content?content=5678
Output www.example.com/somedifferenturl/

@ryanvano The appropriate documentation is here:

I believe what you want would be something along the lines of:

/content content=1234  /someurl  301!
/content content=5678  /somedifferenturl  301!

@nathanmartin Thanks so much. I had reviewed the documentation many times and also searched all over. It was the placeholder vs the actual query string that I couldn’t figure out. This works perfectly.
