Our site moved and we needed to redirect the traffic to the new site. Simple redirects are working to the main page but we ran across a problem that has stumped us.

We need to redirect
marlinsgofast.com/EvSignup.jsp?event_id=463763&team=recmsmhmwa
to
teamunify.com/EvSignup.jsp?event_id=463763&team=recmsmhmwa

(Actually we need to redirect anything with EvSignup.jsp in it). Note this page, or any .jsp pages, do not exist on the old site.

From: EvSignup\.jsp\?event_id=463763\&team=recmsmhmwa
To : teamunify.com/EvSignup.jsp?event_id=463763&team=recmsmhmwa

But I get a 404 error from my host. Note that we do not have any jsp pages in our old site.

I also tried a rule

From: Ev*
To : teamunify.com/EvSignup.jsp?event_id=463763&team=recmsmhmwa

That works for most URLs with Ev in them but never works if there's a . in the URL
For example marlinsgofast.com/EvSignup entered into a browser will redirect just fine but marlinsgofast.com/EvSignup.jsp does not

Even marlinsgofast.com/EvSignup. does not work.

I hope I have explained this clearly. I can't seem to get the expression correct in the From: field.

Thank you

The problem is solved after finally understanding the advice given to other posters of modifying .htaccess to include
ErrorDocument 404 /
