Hi, I know that you can do an XMPP with ports 80 or 443 for this, there are services such as jwchat, and through a web, the configuration is used to use port 80. I need documentation or someone who knows about it. Thank you     

I have a question about the XMPP protocol. My question is how you can do for example in my chat to transfer files without the firewall blocking me since most cases do not leave me.
