Paths with uppercase letters aren't working

ryanburnette · October 22, 2020, 7:31pm

1. Caddy version (`caddy version`):

v2.2.1 h1:Q62GWHMtztnvyRU+KPOpw6fNfeCD3SkwH7SfT1Tgt2c=

2. How I run Caddy:

caddy run

a. System environment:

ubuntu 18.04

b. Command:

c. Service/unit/compose file:

d. My complete Caddyfile or JSON config:

mysite.com {
  root * /srv/html
  file_server
}

3. The problem I’m having:

My customer sends our their URLs on print materials with capitals. I need URL paths to be assumed to be all lowercase. Would appreciate any help the community can offer with how to configure this using Caddyfile.

I’m having trouble finding an answer because there was a v1 bug related to capitalization and anything I find seems to be related to that.

4. Error messages and/or full log output:

5. What I already tried:

6. Links to relevant resources:

When I try

redir /Research /research

for example… I get a redirect loop

So I have no idea how to address the issue as of now

Caddy’s path matcher is case-insensitive:

github.com

caddyserver/caddy/blob/b6e96d6f4a55f96ccbb69f112822f0a923942246/modules/caddyhttp/matchers.go#L228

    
      
          // Provision lower-cases the paths in m to ensure case-insensitive matching.
          func (m MatchPath) Provision(_ caddy.Context) error {
          	for i := range m {
          		m[i] = strings.ToLower(m[i])
          	}
          	return nil
          }
          
          
// Match returns true if r matches m.
          func (m MatchPath) Match(r *http.Request) bool {
          	lowerPath := strings.ToLower(r.URL.Path)
          
          
	// see #2917; Windows ignores trailing dots and spaces
          	// when accessing files (sigh), potentially causing a
          	// security risk (cry) if PHP files end up being served
          	// as static files, exposing the source code, instead of
          	// being matched by *.php to be treated as PHP scripts
          	lowerPath = strings.TrimRight(lowerPath, ". ")
          
          
	repl := r.Context().Value(caddy.ReplacerCtxKey).(*caddy.Replacer)

But you can use a regexp matcher for a case-sensitive match: Request matchers (Caddyfile) — Caddy Documentation

So I should not be experiencing this behavior?

mysite.com {
  root * /srv/html/
  file_server
}

/srv/html/research/index.html

curl https://mysite.com/research/
200

curl https://mysite.com/Research/
404

Well, can it be found? What does ls -la /srv/html/Research output?
