RewriteRule doesn't work with the query part or the URI thus will not work
in your case. You need to try RewriteCond directive combined with
RewriteRule. Something like this maybe?
RewriteEngine On
RewriteCond %{QUERY_STRING} ^(filename=myfile.txt)$
RewriteRule .* - [E=FILENAME:%1]
Header set "Content-disposition" "attachment; filename=%{FILENAME}e"
env=FILENAME
I'm not sure though about the effect of the Header set directive, is it
going to have a global effect afterwords or not?
