I’ve tried to create a simple test case.
v2.0 beta 9
/m/projects/site/project/web/test.php (shows PHP Variables):
<?php phpinfo(32); ?>
The Caddyfile is below, with comments listing results of requesting this URL:
http://www.example.localhost/blog
http://www.example.localhost
tls off
root * /m/projects/site/project/web
# Only one of the three try_files uncommented at a time
try_files /test.php?p={path}&{query} # 404 status: 'File not found.'
try_files /test.php? # 404 status: 'File not found.'
try_files /test.php # shows PHP Variables page
reverse_proxy {
to unix//run/php/php7.3-fpm.sock
transport fastcgi {
split .php
}
}
Am I right in thinking that all three try_files should show the test.php PHP Variables page, as processed and output by PHP? Does adding the ? to the filename result in Caddy looking for a file literally named test.php??
As an aside, I came across this while experimenting: when requesting http://www.example.localhost/?p=1 with try_files /test.php? or try_files /test.php?p={path}&{query} (but not with try_files /test.php) uncommented I get the following:

Git commit 9fe54e1c6025a45cdd531c093bb94d193a8b91a0
When compiling from source and trying again, I found that Caddy can’t connect to the PHP socket (it’s still there, and has permissions of 666).
