simple 301 redirect

hello

i want to make a .htaccess 301 url redirect - but i don't manage it (i read before in the handbook etc. ...)

the path is very simple /blog/blogentry

and it should redirect to /blog/anotherblogentry

the redirect works, but i always get parameters after the /blog/anotherblogentry like /blog/anotherblogentry?=dedwedg

what to do?

thanks and greetings
