Squid服务端配置遇到的问题(80/443)

1>发生了下列的错误：  

Invalid Request

无效的请求

Some aspect of the HTTP Request is invalid. Possible problems:

HTTP 请求的某些方面是无效的。可能是下列问题：

Missing or unknown request method

缺少请求方式或未知的请求方式

Missing URL

缺少网址

Missing HTTP Identifier (HTTP/1.0)

缺少 HTTP 标识（HTTP/1.0）

Request is too large

请求命令过长

Content-Length missing for POST or PUT requests

POST 或 PUT 请求缺少内容长度

Illegal character in hostname; underscores are not allowed

主机名称中包含不合法的字符；下划线是不允许的。

解答：在https_port 后加defaultsite=www.abc.com

2》443端口不listening

解答：证书不正确，请生成可以的证书

附加《1》：用下面命令可以生成测试用的证书：

openssl req -new -keyout key.pem -nodes -x509 -days 365 -out cert.pem

附加《2》：如果要生成一个证书请求用于申请正式证书请用下面两个命令：

(1)、生成私钥 openssl genrsa -out key.pem 1024 
(2)、生成待签名证书 openssl req -new -out req.csr -key key.pem

然后将req.csr文件中的内容提交给证书颁发机构。

3》Unable to forward this request at this time

解答：

在配置中加下面一行

cache_peer www.abc.com  parent 80 0 no-query originserver

为了大家方便比较我贴出我的配置文件，供大家参考
