Send correct hostname when in proxy mode

[vyrus]

When traceGL proxyfies requests to some backend server, it transparently sends something like http://localhost:2080 in Host header of http request. This behaviour may be confusing for your backend if it was configured to use virtual hosts. So we need to add one line to send correct headers:

diff --git a/tracegl.js b/tracegl.js
index 1d6c2f2..4fd8823 100644
--- a/tracegl.js
+++ b/tracegl.js
@@ -4646,6 +4646,10 @@ define('/core/io_server',function(require){
            delete opt.headers['if-modified-since']
            delete opt.headers['content-security-policy']
            //}
+
+           // Send correct hostname to proxified server instead of "http://localhost:2080"
+           opt.headers['host'] = hs.proxy.hostname
+
            req.on('data', function(d){
                p_req.write(d)
            })

Thanks! I'll incorporate this in the next update today or tomorrow

Has this made it in yet? I work with virtual hosts and shit is hitting the fan

This patch introduced other issues when working in proxy mode, like sending websocket requests to the proxied hostname when they should be handled by tracegl.

I am also having this issue, which is preventing me from using tracegl where I would like to. I tried this patch, but it makes tracegl crash (right after it loads the site!).
