Change in error_page behavior

[brianmercer]

I used to use this:

  error_page 497 https://domain.com:7878$request_uri;

to redirect requests from the http://domain.com:7878 non-ssl address to
the ssl version on the same port.  see

This stopped working recently, probably with the latest change to
error_page in 0.8.53.

After some trial and error, it seems to be working fine with this:

  error_page 497 =301 https://domain.com:7878$request_uri;

Is that going to give me the same effect as before?
