comment http header if not modified help
The browser will respect the max-age and expires headers as well, so that might be the issue. You might want to configure Varnish to strip those out before sending the response.

comment http header if not modified help
You can issue PURGE commands to Varnish to remove specific URLs,, so you might be able to find a way to automate this for changes (e.g. wordpress.org/plugins/varnish-http-purge), but like I said, I don't use Wordpress so I can't vouch for specific plugins.

You can still gain benefit from just caching the static files (including images). Varnish will serve these much faster than something like Apache would out of the box.

comment What Will Be The Effects of Multiple NS Recrods For Parked Domains?
In your case, because the different name servers will give back different results, you're effectively splitting your traffic between the two services. Probably not a good idea, as it could give a poor user experience.

comment Why would a url of example.com/n (where n is the same number repeated 500x) return a 403 error?
Does the Apache error log give you a clue as to the cause?

comment Can I declare a duplicate page via javascript for google?
That adsense article is about having your adds as early as possible in the <body>. I don't see how removing a line of HTML code from the <head> is going to make any difference to your ad revenue.

comment Which is better for linking to external resources on a webpage?
If your site forces HTTPS then there is zero difference between the two options.

"I'm not sure how many browsers support protocol-less URLs" - it has been a standard for over 20 years, so I'd guess the answer is 'all of them'.

comment Can generating static links via javascript be legal and recognized?
To be fair there isn't a lot you can improve there. But your time to first byte is 72ms, and then the content download for your HTML page is 33ms. So it takes your server twice as long to generate the page as it takes the browser to download it. I'd probably focus my attention on improving that TTFB figure (so application code or server-side optimisations).

comment what is difference between vps and Dedicated Servers
I think you are confusing a VPS and what some companies call "cloud hosting" (although I agree the terms aren't always used consistently). Basically everything in your list applies to both VPS' and dedicated servers. You have full root access to a VPS - you can install whatever you want on there, although perhaps things are different in the Windows hosting world.

Please cite your sources and indicate that the text is a quote if you cut and paste from a 3rd party website (a hosting company in this case).

comment How to make Google ignore an element on a page (without using HTML comments)?
Google will show the text snippet it believes is most relevant to the user's search query. You'd be better off trying to figure out why it believes your add to cart buttons are more relevant than the other content on the page, and trying to improve that content appropriately.

comment Securing images from browsers and humans
If an unauthenticated user tries to access one of the private image URLs directly, are they prompted for authentication? If yes, then you have nothing to worry about. If no, then that's what you need to fix.

comment www A record will not update to non-www A record?
Where is the 'DNS Zone editor' in which you're editing the records? Your domain's DNS is using *.microsoftonline.com name servers.

comment www A record will not update to non-www A record?
Indeed, it definitely shouldn't take more than a couple of days. At this point we'd probably need to know your domain name to investigate further.

comment How to tell search engines to not index entire image domain without making them waste server bandwidth or making google complain
Just read your other related question. Personally I would just put the robots.txt back in, but use the proper Disallow: / syntax (not noindex). Make sure you're not linking to the root of the image domain anywhere, if that's what the error in webmaster tools was complaining about. If that error persists, allow Google to crawl the root of the domain but not images (i.e. do Disallow: /images or similar depending on what your URLs look like).

How long ago did you make the change?

Why can't you just add a robots.txt to the root of the image domain if you don't want anything on it indexed?
