I am using Bizhat.com as hosting my website.
But unfortunately, i think the upload of FTP through firewall is something troublesome.

I tried using my company internet and I think there is some problem on the proxy side.

I hope Bizhat.com would be able to build a browser base upload file which is easier and also security wise better. I also recommend Bizhat.com to enable ZIP upload and then automatically unzip the zip to the respective domain or subdomain. This will reduce the level of security also.
