How to deal with cross-origin access failure when flex uses proxy to access the Internet

In the LAN, I access the ArcGIS service in another LAN in one flex, but the ArcGIS service cannot be accessed due to proxy access. You can set it as follows:

My local IP Address:

IP address ......: 172.17.41.134
Subnet Mask ......: 255.255.0.0
Default Gateway ......: 172.17.1.111

 

When setting proxy in IE: connection -- LAN Settings -- after setting proxy server, click "advanced": In the exception, set as follows:

 

172. 16. *; 172. 17. *; *. Sina. *; *. ccssoft

 

 

You can access it.

 

Sina. * is generally the domain name of the company. In this way, you can.
