Hi,

I am developing a custom webmin module and since a couple of days I am tryi=
ng to get  a redirection to another page (CUPS on the same server as Webmin=
) to work.

When I am using the redirect-Function (&redirect("https://192.168.1.5:631")=
), the browser shows an error: CORS header 'Access-Control-Allow-Origin' mi=
ssing.

As mentioned in this bug (https://github.com/webmin/webmin/issues/1026), I =
added Access-Control-Allow-Origin: "https://192.168.5.1:631" to Extra HTTP =
headers in the Webmin Configuration but the result is the same. I also inst=
alled the browser add-on mentioned in issue 1026 (https://addons.mozilla.or=
g/en-US/firefox/addon/cookies-and-headers-analyser/) which shows the value =
'"https' for access-control-allow-origin. (By the way I also tried with sin=
gle and without quotation marks.) I don't know much about http headers, so =
I can't tell if Webmin or the add-on are cutting the value at the colon.

I did some further tests: If I use PrintHeader() instead of ui_print_header=
() the link works fine.

I am stuck now and don't know how to solve this problem.

Thanks a lot in advance for hints and help!
Sylvia
