We have a number of spots throughout our experience where there are hard-coded absolute references to images and we are looking to change that. An example would be a reference to an image src of http://www.blahblah.com/images/image1.jpg . This is a no no, but it happened way back quite a bit and not just for images, for videos, files, css, etc as well. We are now moving to https sitewide so these all cause mixed-content issues, so we need to fix... but there are A LOT of them so by hand would take a while.
With that as background, does anyone have suggestions as to the best way to find and replace the content? For the most part we could really just change http://www.blahblah.com to https://www.blahblah.com OR just remove http://www.blahblah.com and leave the reference as /images/image1.jpg. In our case, both should work.
Thanks in advance for any ideas!
