Economia Preproduction Proxy

Connect

This method is for connecting from both internal network and internet. It works in recent browsers (tested Firefox 33 and Chrome 43)

Proxy Autoconfiguration URL:https://preproxy.isrv.cz/proxy.pac

This method uses "secure proxy" with authentication against Economia Active Directory for internet access. User must be in group "Dev-ext-apl", "eco-analytics" or "PP-ext". Internal access is without authentication. The access is automatically switched between "internal" and "external", based on your IP address (check if starts with 10.128., that is office/vpn prefix).

Internal connect (no PAC)

This method is for software that do not support Proxy Autoconfiguration (PAC). It works only from Economia office network.

Server:preproxy-int.isrv.cz
Port:3128

You should use this proxy both for HTTP and HTTPS protocols

External connect (no PAC)

This method is for software that do not support PAC.

Server:preproxy.isrv.cz
Port:3128
Protocol:HTTPS

The protocol (HTTPS) is for communicating with proxy. Note that most software does not support this directly. We recommend to use stunnel (client configuration) for encapsulating the commumication with proxy into SSL/TLS in such case. Then the software must authenticate to proxy using HTTP basic authentication.

Examples of external connect

curl:

curl -U "user:heslo" -x "https://preproxy.isrv.cz:3128" "http://logs.centrum.cz" -vvv

nodejs:

var request = require('request'); const user = 'user'; const password = 'password'; var options = { url: 'http://logs.centrum.cz', method: 'GET', proxy: `https://${user}:${password}@preproxy.isrv.cz:3128`, strictSSL: false }; function callback(error, response, body) { console.log(body); console.log(response); console.log(error); } request(options, callback);
