Detailed explanation of the difference between url ending with / and without / in nginx proxy_pass configuration

When nginx configures proxy_pass, the difference between the URL with "/" at the end and without "/" at the end is as follows:

Note: When location is a regular expression matching pattern, the URL in proxy_pass is not allowed to have a "/" at the end, so the regular expression matching pattern is not within the scope of discussion.

When the URL in the proxy_pass configuration ends with a /, when nginx forwards, it will remove the location matching expression from the original URI and append it to the URL in proxy_pass.

Scenario 1:

location ^~ /test/ {
 proxy_pass http://192.168.171.129:8080/server/;
}

The actual access address after proxy: http://192.168.171.129:8080/server/tes.jsp

Scenario 2:

location ^~ /test {
 proxy_pass http://192.168.171.129:8080/server/;
}

The actual access address after proxy: http://192.168.171.129:8080/server//tes.jsp

Scenario 3:

location ^~ /test/ {
 proxy_pass http://192.168.171.129:8080/;
}

The actual access address after proxy: http://192.168.171.129:8080/tes.jsp

Scenario 4:

location ^~ /test {
 proxy_pass http://192.168.171.129:8080/;
}

The actual access address after proxy: http://192.168.171.129:8080//tes.jsp

When there is no / at the end of the URL in the proxy_pass configuration, if the URL does not contain path, the original URI is directly concatenated after the URL in proxy_pass; if the URL contains path, the original URI is concatenated after removing the location matching expression and the URL in proxy_pass.
