Mudy’s Blog

Long time no update.

I have just added google frame to my blog template. I was trying to find some sites actually use chrome frame without any success. Just out of curiosity I added it to my own website.

Here are screenshots after install chrome frame in my ie8.

Update 1: The display will flick when it switches rendering engine. Ie8 will also switch render engine back when I click a regular webpage.

On Varnish’s official website, there is a WordPress optimization guide For The Impatient: Preparing Varnish/Wordpress for a Slashdotting in 60 seconds or less….

The problem is that it removes cookie too aggressively. All non admin page will be virtually static. So I made my own vcl to remove cookies for only static files.

Here it is

backend default {
.host = "10.25.0.1";
.port = "80";
}
 
sub vcl_recv {
# Normalize Content-Encoding
    if (req.http.Accept-Encoding) {
        if (req.url ~ "\.(jpg|png|gif|gz|tgz|bz2|lzma|tbz)(\?.*|)$") {
            remove req.http.Accept-Encoding;
        } elsif (req.http.Accept-Encoding ~ "gzip") {
            set req.http.Accept-Encoding = "gzip";
        } elsif (req.http.Accept-Encoding ~ "deflate") {
            set req.http.Accept-Encoding = "deflate";
        } else {
            remove req.http.Accept-Encoding;
        }
    }
# Remove cookies and query string for real static files
    if (req.url ~ "^/[^?]+\.(jpeg|jpg|png|gif|ico|js|css|txt|gz|zip|lzma|bz2|tgz|tbz|html|htm)(\?.*|)$") {
       unset req.http.cookie;
       set req.url = regsub(req.url, "\?.*$", "");
    }
# Remove cookies from front page
    if (req.url ~ "^/$") {
       unset req.http.cookie;
    }
}
sub vcl_fetch {
        if (req.url ~ "^/$") {
                unset obj.http.set-cookie;
        }
}

So all interactive pages will be sent to php backend with correct cookies. All static files and front page will be served by varnish proxy.

This plugin will reduce uploaded image size in wordpress.
You will also need to install Optipng , Jhead and unsafe mode php.

These tools will only strip meta information of your images, therefore the result should be lossless.

You can download this plugin here.
