Hotspot Proxy problem

Hi All,

I have a weird problem when trying to redirect web proxy. What i am trying to do is allow users who have proxy server setup as part of the settings in their web browser to access our hotspot without disabling their currenty proxy settings.

I have managed to do this with partial success. It sometimes works and sometimes doesnt.

setup:

/ip hotspot profile

HTTP Proxy: IP of our MikroTik
HTTP proxy port: 3128

we have enabled the web proxy in mikrotik.

When i try to access the Hotspot with proxy settings enabled on my web browser sometimes it works fine and some times i get an error message incating that a java script has not loaded correctly and it doesnt load externally held images banners etc correctly.

has anyone come across this error or have a better solution for me.

Kind Regards,
Michael Huynh
