One of the comments on the documentation page of mod_proxy_fcgi (http://httpd.apache.org/docs/2.4/mod/mod_proxy_fcgi.html) mentions an issue with flush:
There is just no flush support it seems. I attempt to use PHP flush() and it won't work until you fill up a buffer first, rendering Server Sent Events impossible with proxy_fcgi. It worked very well with "-flush" with mod_fastcgi FastCgiExternalServer. If this is really the case, all web applications that use push notifications won't be working with mod_proxy_fcgi. The wiki page on https://wiki.apache.org/httpd/php also suggests to use mod_proxy_fcgi, but if above is true, this might lead to problems. What is your take on this? -- regards Helmut K. C.
