Nginx: keep ngx_pageespeed up to date

If you use the Nginx-Pagespeed module - like I do on tech-blogger.net and routerzwang.de - you should keep it up to date. This can save you a lot of troubleshooting. If you already compile Nginx itself and use the module "ngx_pagespeed", you not only have to keep Nginx up to date, which brought HTTP/2 support in the last versions, but also the ...

Nginx with SSL and SPDY

As some of you may have noticed, my blog kadder.de is now running over an encrypted connection (recognizable by the HTTPS icon in the browser bar). The main reason for this change, which unfortunately costs some time at first byte time, was the possibility to offer connection via SPDY for corresponding browsers (e.g. Chrome). Also, I was interested to see how ...
