Here is some simple troubleshooting for Varnish
This topic has always been a big pain in the ass for me. Drupal takes a lot of resources, which means money for hosting, you should at least have VPS to have some decent hosting for drupal, but not to have OOMing and high CPU usage all the time, you should use different caching systems.

If you ever wondered how to setup permission and ownership of files on your drupal server installation, look no further, this article has all the good examples.
So Varnish is really good caching thingy if you use drupal (or other stuff) so to see what it is doing and how, you can login to your server and try this commands.
varnishlog - See what Varnish is currently processing, you will get complete header info I think
varnishstat - Shows various information about varnish
So this is some marketing stuff I do, but it is useful. When you click a link on some site, to give some message to that site and owner or whoevere is taking care of marketing you can add some UTM tags to links so in their google analytics they see that message. So what do we do is I use display suite, create custom code field and use entity data to make new fields that look like this:
I wanted to have phone call tracking on my website, so I know how many users did click phone number to call over cell phone or phablet or whatever device they can call (maybe google glass or something) So I added some code to my phone fields.
Drupal is great :)) well not so much, it is made in a way that you will always have love/hate relationship with it. So somebody thought that best way to make templates is to have title and h1 tag always in page template separated from the rest of the content, which is fine if you are doing pages in 2002.
If you display your webform as block and then also use Full Node view in block settings, you will have a title that leads to the webform itself. Probably you don't want to do that. But what to override, it's kind of simple, just override node--node_id.tpl.php as this is in the end a node display and remove link from h2 tag. That is all.
So this one is rather old in 2013. But then again Ubercart and E-commerce are slowly getting up to speed with drupal 7 so still many sites use Drupal 6 for web shops. Anyhow, what we wanted to do is add some extra information to emails sent after order. Ubercart has a way of sending nice HTML emails to clients and obscure plain text emails to admins.
Without a powerful server drupal administration online is very slow. As I have a multisite online, for some bigger changes I decided to take it offline to localhost and try to build/change things on my computer an then upload DB online. But first I needed to configure my localhost to work with multisite.
