Trailing Slash Redirect Loop Help

April 28, 2017 10:27AM
Hi,

I am having an issue getting rid of the trailing slashes for directories. I have used the following to get rid off the trailing slash:


#rewrite all URIs without any '.' in them that end with a '/'
#rewrite ^([^.]*)/$ $1 permanent;

&
#rewrite all URIs that end with a '/'
rewrite ^/(.*)/$ /$1 permanent;

They both work, but they do not when it comes to directories. When it is a directory the page is not displayed because it has different redirects. Here is the code that I have used inside the LOCATION definition as well as in the SERVER block and they just do not work.


if (!-e $request_filename) {
rewrite ^/(.*)/$ /$1 permanent;
}

Or, I have used this one:

if (!-e $request_filename) {
rewrite ^([^.]*)/$ $1 permanent;
}

Note: I have tested individually the two rules either in the server block or the location block and I still get the redirection problems with files or directories.


Could any of you please help me and tell me what I am doing wrong. Basically, when I enable the rewrite rule to get rid off the trailing slash all directories get multiple redirects and end up in a loop.

Here is the nginx configuration.

worker_processes X;
pid /xxxx.pid;

events {
worker_connections xxxx;
# multi_accept on;
