Change backend during retry in Varnish 4

由 狂风中的少年 提交于 2019-12-19 05:59:31
问题 I'd like to be able to change the backend on a retry in Varnish 4. We've got this working on a different (older) application using Varnish 3, but I haven't been able to figure it out for v4, nor find much documentation. The setup we want is to have 2 sets of directors - one for the initial request trying a local server in the same datacenter as varnish because this is way faster, and then only if that fails, pick randomly from a different director for servers in other datacenters. In v3, this

Varnish C VRT variables/functions

由 廉价感情. 提交于 2019-12-12 15:53:32
问题 I'm starting to pick up varnish and have come across references to VRT functions in C code in our configuration (and examples on the net) that I can't find documentation on (that I understand, my C knowledge is non-existant). This is the best I can find but it's just the prototypes: http://fossies.org/dox/varnish-4.0.2/vrt__obj_8h.html#a7b48e87e48beb191015eedf37489a290 So here's an example we use (and which seems to be copypasta from the net as I've found it plenty of times): C{ #include

replacing content in a page with varnish + regex

由 扶醉桌前 提交于 2019-12-10 13:45:26
问题 If I want my varnish cache server to replace content inside a page (ie: change the class on a div) from the backend before serving or storing the page (vcl_fetch?), how can this be done? I would like to use simple regex to perform the replacement as I imagine it is supported natively in varnish. 回答1: Modifying response body is not natively supported by Varnish. You need a Varnish module (vmod) for this. Aivars Kalvans has libvmod-rewrite, which does exactly what you are looking for. However

Varnish not processing ESI includes

由 落爺英雄遲暮 提交于 2019-12-10 11:52:38
问题 I'm trying to setup Varnish to process ESI includes on a local environment. I am running varnish in a virtual machine and the content is running on the host machine. I have two files "index.html" and "test.html". These are both stored in a folder called "esi" in the docroot of an apache server. index.html <h1>It Works!</h1> <esi:include src="test.html" /> test.html <p>ESI HAS BEEN INCLUDED</p> Varnish is running on the virtual machine on port 8000. So I access it here: http://192.168.56.101
