Re: Configure varnish to pipe a subdomain
Erik [EMAIL PROTECTED] writes:
Neither am I a regex expert, but I dont think that the regex is the
problem. You are using http.url instead of using http.host. And if
im not totally wrong, you dont need the ~ to check the host, you can
use ==.
Change this:
if (req.http.url ~ admin.example.com$) {
pipe;
}
To this:
if (req.http.host == admin.example.com) {
pipe;
}
And this:
if (req.http.Cookie req.http.url ~ admin.example.com$) {
pipe;
}
To this:
if (req.http.Cookie req.http.host == admin.example.com) {
pipe;
}
A couple of issues:
- a regexp is better if you get it right, because a regexp match
(unlike a string comparison) is case-insensitive by default.
- pass is better than pipe, unless pipe is required for other
reasons, in which case Connection: close should be added to the
request headers.
- the second if will never evalutate to true, since the first one
trumps it.
The correct code would be:
if (req.http.url ~ ^admin.example.com$) {
pass;
}

You didn't say which version you're using, but from this backend

know whether you see the same behaviour with trunk.
Hi,
I tried trunk and I don't get any blank page with it. I'm sorry I
didn't try it earlier.
if (req.http.Pragma == no-cache) {
pipe;
}
Are you sure you want to do this?
If the point of this is to allow the client to Shift-Reload, you
should purge the URL to force a reload from the backend, instead of
piping the request.
That's the point, I just needed a quick way to purge an URL.
Later I'll definetely purge it from the backend.
Thanks for your reply, I'm still learning a lot about Varnish,
especially the difference between pass and pipe. Actually the pipe
for POST and req.http.Expect were taken from the default vcl.
If I understand correctly pipe means that further data between
client and server is passed until the connection is closed, while
pass means that the current request will be passed, but further
requests in the same connection will be normally processed by the vcl
file (and could be looked-up, for example).
Is this correct? Would you please make some examples where pass and
pipe are preferred?
Thanks,
Marco

That's the point, I just needed a quick way to purge an URL. This won't do what you want; the client that used Pragma: no-cache will see a new version, but other clients won't. Additionally, I would recommend that you use an ACL to restrict purging to specific clients. Thanks for your reply, I'm still learning a lot about Varnish, especially the difference between pass and pipe. Actually the pipe for POST and req.http.Expect were taken from the default vcl. The *old* default VCL :) I haven't had time to update the documentation. If I understand correctly pipe means that further data between client and server is passed until the connection is closed, while pass means that the current request will be passed, but further requests in the same connection will be normally processed by the vcl file (and could be looked-up, for example). Absolutely correct. Is this correct? Would you please make some examples where pass and pipe are preferred? pass is preferred whenever possible; pipe should only be used for requests that Varnish can't handle at all because they don't follow the ususal HTTP structure (CONNECT is the only example I can think of at the moment) In the past, pass could not handle POST requests at all; later, it could handle them but poorly (insufficient error recovery). The current code in trunk handles POST requests correctly in pass mode.

error page not delivered
I am unable to get varnish to deliver the customized error page when requesting a non-existent url. I should correct the above statement to I get a blank page when requesting a non-existent directory or html file in the url.
