nginx (or PHP?) sends wrong Location in HTTP header


Engine: nginx-1.10.1_2,2
App language: php70-7.0.12
CMS: Symfony 1.4

I have a problem with Location in HTTP header.

Old server (Apache, PHP5) reply for all browsers:

New server (nginx, PHP7) reply for all browsers:
: http: //

The above generates problem only on Edge & IE which cannot handle it during login redirection.
I've forced to add Location HTTP header in nginx but I think it's not a solution. It generates another problem although login redirection works properly.

Please read a post on where all I've described with details.

Thanks for your help.

                location ~ \.php($|/)
                                set  $script     $uri;
                                set  $path_info  "";

                                add_header      Location        $script always;
Because on TCP stack in data field "Location:" is not available. Instead of that I have ": http: //" and I suppose that Edge&IE cannot parse it or do it strange things to "Hmm, we can't reach this page."
I investigated it through Wireshark. So I added the header for Edge&IE that they could understand what should they do.

I was trying a lot of nginx examples and for me works mine.
It was difficult because I transferred web data to the new server from very old one (2008 year) which has not been updated completely and where were old Apache and PHP5.
Why didn't you use Apache for the new server? The configuration would be mostly the same, so it'll be easier to move the site to a new install.
Symfony 1.4 has problems with php55 and you set up php70. Did you checked requirements before migration?
No. I migrated with some code changes and all works fine except one thing described in this thread.
I always use up to date apps knowing that some problems could occurred.
