Nginx loses POST variable with http -> https redirect

Question

I have a website set up that uses the redirect method...

server {
    listen 80;
    server_name example.org;
    return 301 https://$server_name$request_uri;
}

However when a page is posted to "http://example.com" it redirects to "https://example.com" and in the process, it strips the POST.

I recognize this is how it works, however I need to somehow do one of the following...

• Do a redirect from http -> https while keeping the POST variable intact
• Convert the POST variable to a GET variable during the redirect (which would work fine)
• Redirect everything EXCEPT for one folder

Any suggestions? I'm a bit lost...

Answer 1

If you are willing to forgo the "permanent" redirect status, I believe a 307 redirect instead of a 301 will preserve the POST. There actually is a redirect that is permanent and preserves the post, a 308, but it isn't well adopted yet by browsers and other user agents.

Answer 2

A 308 redirect is a fix, but the solution is to POST directly to https:

• by posting to http, your post data are not secure
• the redirect make the process slower
• if you post to http from an https webpage, browser may display a warning to the user
