I have a same site deployed on 2 different servers, The source files on the servers are identical, so I have to assume what is being sent by webservers on servers are different, as one has javascript that works in IE11 and the other server sends something that breaks the Javascript on the very same page and input (posted data).
How do I either save all the resources sent to a request or use IE11 F12 tools to save all the received resources?
Is there any tools for emulating browsers and saving all the sent responses to disk? (I tried saving the network traffic in IE11 to disk , but there are details about reponse times etc, that are making a compare extremely difficult).
You can save all the files delivered by the server to IE11 by clicking the Page button, then choosing Save As. Select Web Page, complete to save all the files.
The first thing to check would be to use the IE developer tools to watch for errors as the page loads.
