nginx rewrite 导致验证码不正确

配置nginx里url rewrite的时候，为了使浏览器地址栏的URL保持不变，

使用proxy_pass反向代理，但发现每次都会生成新的jsessionid

 

解决方法，配置中增加  

proxy_cookie_path /two/ /;


官网说明如下：

Syntax:	proxy_cookie_path off; proxy_cookie_path path replacement;
Default:	proxy_cookie_path off;
Context:	http, server, location

This directive appeared in version 1.1.15.

Sets a text that should be changed in the path attribute of the “Set-Cookie” header fields of a proxied server response. Suppose a proxied server returned the “Set-Cookie” header field with the attribute “path=/two/some/uri/”. The directive

proxy_cookie_path /two/ /;

will rewrite this attribute to “path=/some/uri/”.

The path and replacement strings can contain variables:

proxy_cookie_path $uri /some$uri;

 

The directive can also be specified using regular expressions. In this case, path should either start from the “~” symbol for a case-sensitive matching, or from the “~*” symbols for case-insensitive matching. The regular expression can contain named and positional captures, and replacement can reference them:

proxy_cookie_path ~*^/user/([^/]+) /u/$1;

 

There could be several proxy_cookie_path directives:

proxy_cookie_path /one/ /;
proxy_cookie_path / /two/;

 

The off parameter cancels the effect of all proxy_cookie_path directives on the current level:

proxy_cookie_path off;
proxy_cookie_path /two/ /;
proxy_cookie_path ~*^/user/([^/]+) /u/$1;
