ssl - Curl keeps saying "SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure" but it should be TLS -


the php version on webserver updated. notice when downloading external https urls curl, one specific server fails, giving me error:

ssl23_get_server_hello:sslv3 alert handshake failure

downloading https stuff server though curl worked fine before.

now strange is: seems ssl3 error, understood other cases regarding error (also here on so) it's due ssl3 no longer being supported updated versions of php or curl. , rightly so, since ssl3 insecure.

however, particular webserver uses tls1.2, , no means ssl3.

so if curl not using ssl3, , neither webserver, why still getting ssl3 related errors?

i tried setting curlopt_sslversion 4, 5 or 6, , setting curlopt_ssl_cipher_list tlsv1, no avail, error keeps coming up.

although error message looks using ssl 3.0 not. since tls1.0 practically ssl3.1 etc find lots of functions , error messages having sslv3 string within tls code path in openssl. problem specific server else , 1 need know server hostname , installed version of openssl find out more problem.

edit: based on comment version of openssl used curl 0.9.8b. since server can tls 1.2 handshake fail, since tls 1.2 supported since openssl 1.0.1. apart 0.9.8b years out of support , has several security problems got fixed in later versions.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
