double slashes redirection

[B.R.]

By default, nginx 'cleanse' URI by decoding/correcting specific cases
before matching it against a location. The multiple slashes are part of it.
Read how location
<http://nginx.org/en/docs/http/ngx_http_core_module.html#location> works.

I suppose the internal $uri
<http://nginx.org/en/docs/http/ngx_http_core_module.html#var_uri> variable
holds watch nginx uses for its logic, but in any case holds a
decoded/corrected version of the URI.

If you *do not* want nginx to automatically try to correct multiple
slashes, you can override the default configuration for the corresponding
merge_slashes
<http://nginx.org/en/docs/http/ngx_http_core_module.html#merge_slashes>
directive.
Be careful then: your locations won't match if they do not find any exact
stanza suitable for them. ;o)

You will be up for the pain you asked for...
