Browser is long time no response when set port 80 at v2.0.0.
I use wireshark and find no http packets between browser and router.
Maybe a firewall issue?
My envirement is openwrt15.05 with libmicrohttpd library.
(V2.0.0 with other port is ok; V0.9 is ok at port 80.)
In normal operation as a hotspot, https support is not needed as all devices these days do an initial request on port 80 via their built in Captive Portal Detection regardless of any "home page" that may be set in the browser. So the build will be for libmicrohttpd-no-ssl to remove unnecessary code and significantly reduce the installed size.
It would be a nice thing to have https support for some specialised applications, but would always produce a certificate error as far as I can see.
