[Web 开发] URL 的最大长度
Web开发的常见问题： "URL 的最大长度是多少？"
答案是：
HTTP协议标准并没有规定URL的最大长度。
RFC文档： http://www.w3.org/Protocols/rfc2616/rfc2616-sec3.html#sec3.2
The HTTP protocol does not place any a priori limit on the length of a URI. Servers MUST be able to handle the URI of any resource they serve, and SHOULD be able to handle URIs of unbounded length if they provide GET-based forms that could generate such URIs. A server SHOULD return 414 (Request-URI Too Long) status if a URI is longer than the server can handle (see section 10.4.15).
Note: Servers ought to be cautious about depending on URI lengths
above 255 bytes, because some older client or proxy
implementations might not properly support these lengths.
虽然标准没有规定长度，不同的浏览器对URL做一定限制。 IE的URL长度上限是2083： http://support.microsoft.com/kb/208427
