And if so, what does it do?
I’ve noticed it in some html written by a former co-worker (so I can’t ask the author). I’d guess it was a typo, except that it’s in a couple different places in a couple different templates, used as the source attribute for an image.
For example:
<IMG height='6' src='ihttp://www.ourdomain.com/images/f2f3f4.gif' width='5'>
The top google results point to some sort of apache/php/mysql installer, but we’re running IIS, so I can’t imagine that that’s related.
Typo. Nothing More.
No such protocol exists. What you are seeing is a classic design pattern called cut-and-paste. If I have to guess, I would say that
iwas previously the leadingiinimages/f2f3f4.gif.
