ob_start difference between https and http?


Is there a different behaviour for ob_start, ob_end_flush, ob_end and ob_flush in https compared to http?

I have read the posts about difference between http and https:

Difference between http and https

Difference between HTTPS and SSL

as I have read this one about ob_start & headers:

Showing error pages when sending header with header() function

but I do not find the answer I need.

My Case:

I am flushing a loading image with ob_start on two websites. They are using the exact same code. The only difference is the protocol - one is http and one is https.

The http one acts fine

The site using http outputs the image and will then continue with the script.

The https one acts different

The site using https outputs the image always after the script has been completely processed.

Thanks. I am glad for any hint.


Solution

  • I see two possibilities:

    If you're using php-fpm, try http://php.net/manual/en/function.fastcgi-finish-request.php

    If you're using nginx, try http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_buffering
