I'm looking to perform cross-domain requests on my localhost in developer mode. I work on Opera. So I used the following command to disable web security since Opera is based on Chromium:
cd c:\Program Files\Opera\
launcher.exe --disable-web-security --user-data-dir="c:\nocorsbrowserdata"
according to this Stack Overflow question. It did open a new instance of Opera for me with the following message:You are using an unsupporting command-line flag: --disable-web-security. Stability and security will suffer to certify that web security has been disabled. But when I try to perform a cross-domain request, I get CORS related errors. So I tried disabling web security on Chrome thinking it was a browser issue using the following command:
chrome.exe --user-data-dir="C:/Chrome dev session" --disable-web-security
It gave me the same message as in Opera but I still didn't get there to perform cross-domain queries. I still don't understand because I was certified on several stackoverflow questions that I could make cross-site requests by disabling web security.
