RE: [xep-support] Displaying images from sites with https redirects

Thanks for the suggestion Steve.

I can't really modify the port. I could also just hardcode the 'https'
to the URL, but as it is now I'm trying to find a way to allow the
redirect to occur without modifying the URL that I use...and still get
the image to appear. Does anyone know if this is possible?

Can you include the correct port in the offending URLs
(http://ashhra.enetrix.com:443/ ... or
https://ashhra.enetrix.com:443/...) in the source?
