port triggering vs port forwarding

Nginx can be easily configured as a reverse proxy server: server { listen; server_name localhost; Location/{ Proxy_pass http://x.x.x.x:9500; Proxy_set_header Host $host: Proxy_set_header x-real-ip $remote _addr; Proxy_set_header x-forwarded-for $proxy _add_x_forwarded_for; Proxy_set_header Via "Nginx"; } } However, if the Nginx listening port is not the default 80 port, change to a different

Recently I took over a bug. It is strange that the WebService released by the product does not work and the error "connection refused" is returned. After checking, all the WebService calls reported by the error come from the server's local machine, that is, the WebService released on the local machine is called in the code of the local machine. It's ugly, but it won't report an error. After some investigation, we found that the access from the client to the server was not allowed directly, b

Use the IIS application request Forwarding (ARR) to achieve integration and sharing of port 80 between IIS and tomcat. Currently, the methods for implementing iis and tomcat to share port 80 on the Internet are implemented based on the isapi_redirect plug-in. My implementation methods are different and the principles are similar, which has better advantages. The

First, we use Webpy to write a simple website, listen to 8080 ports, and return to the "Hello, everet.org" page. Then we use our forwarding.py to build two communication pipelines between the 80 port and 8080 ports for two-way communication. At this point, we have access to our servers via port 80. The browser gets: We can then see the communication between the browser and the webpy in the output of the

Label:Transfer from http://blog.sina.com.cn/s/blog_484d87770102uxi6.html Use VirtualBox for a long time, a lot of usage is not deep drilling, really is not open-minded learning ah.Because the default approach is to use NAT for virtual machine networking, it can be cumbersome to access the virtual machine's applications from outside the network. Used to bridge the way, but the IP is limited, its own designated IP may conflict with the LAN IP, and the IP obtained by DHCP may change lead to uncert
