Re: eTags. I'm not sure how to get rid of them. The following code is at the very top of my .htaccess file. I was under the impression that the bottom few lines of this code should take care of eTags, but WebPageTest still indicates eTags are present.
Code:
<ifModule mod_expires.c>
ExpiresActive On
ExpiresDefault "access plus 1 seconds"
ExpiresByType text/html "access plus 1 seconds"
ExpiresByType text/css "access plus 31536000 seconds"
ExpiresByType text/javascript "access plus 31536000 seconds"
ExpiresByType application/javascript "access plus 31536000 seconds"
ExpiresByType application/x-javascript "access plus 31536000 seconds"
ExpiresByType image/ico "access plus 31536000 seconds"
ExpiresByType image/gif "access plus 31536000 seconds"
ExpiresByType image/jpg "access plus 31536000 seconds"
ExpiresByType image/jpeg "access plus 31536000 seconds"
ExpiresByType image/png "access plus 31536000 seconds"
ExpiresByType image/bmp "access plus 31536000 seconds"
</ifModule>
<ifModule mod_headers.c>
<filesMatch "\\.(ico|pdf|flv|jpg|jpeg|png|gif)$">
Header set Cache-Control "max-age=31536000, public"

Re: favicon.ico
Actually, believe it or not, but my original Favicon used to be 15K in size! It contained I think three different icon sizes. I only yesterday got around to quickly reduce it, but I think it still is over 1K. I will play with it a bit again to see if I can reduce it more.
I'm not sure if I have the caching if the favicon set right, as WebPageTest doesn't show this information for Favicons.
Thanks much for your feedback.
