Re: [Lurker-users] How to prefer HTML if a message has both plain and HTML?

[Kaz K. <ka...@ky...>]

 

Hi Wesley, 

Thanks for taking the time to follow up to all my postings. 

I see what is going on in the code with regard to HTML; basically it is
gutted! 

Doing this properly requires a filter which strips out dangerous tags,
while keeping the safe subset of the markup. 

I am experimenting with a patch which just sticks in the raw HTML. Later
I will add some filtering on it, and also treatment of cid: URL's for
proper display of inline images. 

What I have so far is this: 

 	* I made the code which handles multipart/alternative messages to
prefer the HTML part, rather than the plain part.
 	* HTML is not stripped at all, or subject to any special handling.
Instead, the raw UTF-8 is wrapped in an XML CDATA block.
 	* In the UI XSL code, I put in a template rule that a mime body part
matching the "text/html" content type is copied, but with escaping
disabled.

This mostly works the way I want, modulo safety, and handling of links
that point to attachments. 

I may implement the HTML filtering via an external program that will be
configurable in the lurker.conf.

I don't want lurker to show embedded javascript or links or what-have-you to a user. So, I think the current default is the best option for most people.
