<div dir="ltr"><div><div>Thanks guys,<br></div>Pretty much consistent with what I was expecting. I do think as a general rule if you're deploying new infrastructure, you should be forward thinking, rather than configuring only what's required currently, so going forward, there's one less touch point, and if the server/apps team want to configure Forward, it's just there, rather than it being another requirements cycle, but that's just me.<br><br></div><div>Kind regards<br><br></div><div>Paul Wilkins<br></div><div><br><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On 25 April 2017 at 13:48, Colin Stubbs <span dir="ltr"><<a href="mailto:colin.stubbs@equatetechnologies.com.au" target="_blank">colin.stubbs@equatetechnologies.com.au</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div><br></div><div>I’d agree with all of that; though this is actually the first I’ve heard of RFC-7239 actually being used.

My understanding is X-Forwarded-For is widely deployed, widely parsed, and not standard. RFC 7239 is a (proposed) standard, barely deployed, and mostly ignored. Would best practice, going forward, be to include both headers (if you were say, writing i-rules for such things)?<br><br></div>Kind regards<span class="m_7259252667377663121HOEnZb"><font color="#888888"><br><br></font></span></div><span class="m_7259252667377663121HOEnZb"><font color="#888888">Paul Wilkins<br></font></span></div>
