very good! i wanted this!
I just want to add a header Content-Type: application/json for localhost url but it doesn't work
Love it , As Youtube is blocked in my University so I replaced Youtube.com with Youtube-nocookie.com and watch?v= with embed/ . More I can also watch playlists etc...
I use this app to keep me focused when going to YouTube or Facebook by redirecting each to a specific page on that domain. For example, on YouTube, I redirect to a specific channel and on Facebook I redirect to my business page. Other extensions will loop if you are redirecting to the same domain but this one doesn't. That makes it much better than the 5 other extensions I've tried for this purpose. Thanks!!
Super. It work wonderful!
Great, redirects Prod CSS/JS to Local, without installing Charles. Works great.
It does it's job pretty good. I used it for reducing my image quality with rsz.io to save bandwidth.
Loved it for the "Replace part of the URL" feature. Neatly developed. Thanks.
This handy extension allowed us to solve a tricky problem with an iPrism Web Filter. We needed the https youtube links to be changed to http (non-ssl) links for the proxy server to filter and log this traffic in our corporate environment. Some documentation would be a great addition to the extension, but I was eventually able to figure it out through trial-and-error testing.
Does exactly what's expected.
