URL based image links don't appear to be working

[RickStrahl]

Moving one of my Help Builder repos over to Kava Docs and one of the topics has hard coded Web image URLs like this:

![](https://weblog.west-wind.com/images/2014Windows-Live-Writer/Web-Load-Testing-West-Wind-WebSurge_EBFD/Sessions_2.png)

When this renders it ends up getting fixed up as if it were a relative file link:

<img src="https://raw.githubusercontent.com/RickStrahl/WebSurgeDocumentation/master/User-Guide/https://weblog.west-wind.com/images/2014Windows-Live-Writer/Web-Load-Testing-West-Wind-WebSurge_EBFD/Sessions_2.png">

Note the raw.githubusercontent.com bits which shouldn't be applied to any http:// or https:// links.

So it looks like this is happening in the Markdown Renderer that's doing plain string replace which isn't going to work for selective searching. I think this will require loading the content into HtmlAgility pack after rendering and look at links explicitly. I suspect we'll need this anyway for link parsing.

Not good though - this is slow.

Also looking at the renderer I wonder if you should be caching the Markdown Parser build pipeline.
