使用curl提交post请求到服务器被squid代理拦截

原文地址：http://dade.io/archives/25/

做网盘，上传文件到服务器时（服务器使用squid做代理），遇到下面的错误提示：

百思不得其解，查看PHP文档时，笔记中发现如下说明：

Sending a post file upload across a squid proxy, the request was rejected by the proxy. In the error page returned it provided among other possible causes:"Expect:" feature is being asked from a HTTP/one.zero. 

Solution: Add the option <?php curl_setopt($cl,CURLOPT_HTTPHEADER,array("Expect:")); ?>. This will remove the expect http header.

按照方案去掉“Expect：”的header头，OK！

文档还是挺有用的，希望能帮到各位！
