Alright, up and running with Varnish successfully. Quite happy with
Varnish. Our app servers no longer are failing / overwhelmed.
Here's our new problem...
We have a lot of logging going on in our applications. Logs pages, IP
info, time date, URL parameters, etc. Since many pages are being

It has been my experience that anti-DoS is usually easiest to implement at the
origin server level, where the request handlers are typically more flexible and
easiest to program. Even forking servers like Apache can issue 4xx responses
lightning fast, without many resources being consumed.

Well, again, I believe I've solved my own problem with my VCL through
trial and error :)
Managed to get Varnish stripping out the cookies on pages we want to
cache and don't care about cookies on.
Pretty impressed with Varnish.
Is there a place to submit bug tracking items and feature requests f
Thanks David,
I do monitor the memory and cpu load but there seem to be no apparent
increase when this happens.
I should point out that I run this in on a hosted VPS but I am well
below their memory and cpu requirements.
Varnish does restart itself gracefully when this happens. I guess if

I managed to perfect the caching of our pages spitting out cookies
through trial and error.
So this page for instance now caches in Varnish even though the
cookies come along with the page:

I wanted to describe this in better degree to see if anyone can
recommend a way to get Varnish caching these sorts of pages.
This page:

If I look at underlying data via curl:
HTTP/1.1 200 OK

The antiDoS features would be a good enhancement to Varnish. I
realize it's a very complex and resource intensive thing to approach.
There are likely many other ways some of these functions could be used
in other ways for other solutions.
In our instance we are not experiencing a true denial of s
Thanks Ken, you input is very valuable to me. There's so much to
learn from others using Varnish. Very impressed with Varnish and
community.
I took the approach of blocking IPs at firewall level to protect our
app servers. Lots of these banned IPs are malicious, hack attempts -
others are repeti

Firstly, by being damn fast.
Originally we had some plans for specific antiDoS measures, something
like:

When I read this messages, theres something I miss, too.
Some function in varnishd, similar to the lighty/apache mod_evasive.
It enables you the possibility to create dynamic hit/connection rate
depending blocking of ips.
How can varnishd help me prevent DDOS / DOS attacks ?
