I need to connect to a webservice which is behind of a VPN via PHP. My server is Debian Linux (Squeeze).
- Is it possible to accomplish this via PHP on Linux?
- Is it risky to do this if it is possible? (When VPN connection hangs etc., does the operating system or any other what-so-over handles the situation)
- I have only one network card, therefore I really wonder whether it is possible to keep server online for normal users while "posting data over an accomplished VPN connection in the background".
Although my question seems to a conceptual question, any specific help is also welcome.
Server OS : Debian Linux Squeeze (x64)
Web Server : Apache HTTP
PHP Version: 5.3
Framework: Symfony 1.4
