Apache 413请求实体太大而大字符串

Question

最近我改为专用服务器，我开始遇到问题，在jquery ajax帖子中保存大字符串。在旧的服务器工作正常，但在这个新的服务器我得到一个Apache 413错误。

谷歌搜索我发现错误是在LimitRequestBody的大小，我将其更改为64Mb但我仍然收到此错误。

任何想法如何解决这个问题？

Answer 1

这对我有用：

在modsecurity.conf文件中

在我的Ubuntu 14.04上，配置文件在这里，但这实际上取决于系统：/etc/modsecurity/modsecurity.conf

将这两个命令更改为此值：

SecRequestBodyLimit 13107200

SecRequestBodyNoFilesLimit 13107200

Answer 2

LimitRequestBody可能不是你想要的。这是请求主体，而不是标题，它看起来太长了。尝试将the LimitRequestFieldSize（默认为8k）设置为更大的值（请注意有关此设置优先级的警告）。

Answer 3

您可能会遇到SSL重新协商缓冲区溢出情况。检查Apache日志文件。如果是这种情况，快速修复是使用SSLRenegBufferSize指令来增加重新协商缓冲区。见SSL Renegotiation with Client Certificate causes Server Buffer Overflow
