How can I customize the error pages Google Chrome/Chromium displays when there is a networking error (e.g. Error 137 net::ERR_NAME_RESOLUTION_FAILED)
I'm talking about these kinds of pages: http://i41.tinypic.com/29qm8v6.png
They don't seem to be stored anywhere on the file system. Can the errors that make them display be trapped using an extension?
Thanks for any advice.
No :( Correct link at this moment: https://chromium.googlesource.com/chromium/chromium/+/master/chrome/renderer/localized_error.cc
No, trapping is not possible, and the HTML for the error pages gets built at runtime from compiled resources. See http://src.chromium.org/viewvc/chrome/trunk/src/chrome/renderer/localized_error.cc?view=markup for the code that builds these error pages.
