[Xymon] (Take 2) Re: Using proxy for http requests

[J.C. Cleaver]

(Sorry, hit 'Send' a little too early there.)


Agreed that that's probably something that should be taken into account as
well.

The key is the principle of least surprise for a sysadmin who's monitoring
things. As to whether presuming the system proxy should be used or whether
we should assume that testing http://www.example.net/ means testing just
that, I'm not sure the answer to.

There other big issue, in particular is that there's no specific syntax
for *ignoring* a proxy, so before any sort of global override is allowed,
there'd need to be a means for that.
