电脑版微信，公司要求必须使用squid代理服务器连接才能使用，目前遇到的问题是发送消息正常，但无法发送图片、文件。除微信外，其他应用访问都正常。请问如何配置squid代理服务器才能使微信正常发送图片和文件，谢谢。附部分配置。 acl SSL_ports port 443 acl Safe_ports port 443 # https acl Safe_ports port 80          # http acl Safe_ports port 21          # ftp acl Safe_ports port 70          # gopher acl Safe_ports port 210         # wais acl Safe_ports port 1025-65535  # unregistered ports acl Safe_ports port 280         # http-mgmt acl Safe_ports port 488         # gss-http acl Safe_ports port 591         # filemaker acl Safe_ports port 777         # multiling http acl CONNECT method CONNECT # # Recommended minimum Access Permission configuration: # # Only allow cachemgr access from localhost http_access allow manager localhost http_access deny manager # Deny requests to certain unsafe ports http_access deny !Safe_ports # Deny CONNECT to other than secure SSL ports #http_access allow CONNECT !SSL_ports
