Hello all,
First let me say thanks to everyone for taking time to work on this
project...I am still in the testing phase, however if all goes well
Varnish is going to come in quite handy.
So here is my problem:
I would like to use varnish to cache urls for say a period of 30
minutes. The caching seems fine as long as I use the same browser to
request the url. But I am looking for a stop gap solution at this time
so in the event that the web server becomes unavailable....varnish can
serve the docs for a little while, so we can get things back in order.
Anyway..as it stands right now..I can request a url from wget or GET or
firefox... and turn off the webserver and I can refresh the page and all
is well.
What I cannot do...is request a url using GET on one machine..then stop
the webserver and request that same url from firefox (different machine)
and get a valid page...I get a 503 error...Here is the vcl.conf file
(which I took most of from the web) I am using:
Any help would be great!
Thanks,
Shain
