A few years back this list helped me create some locations that allowed  
some extensionless files to run as php and pass the rest of their path  
along as a variable. I’m wondering if there’s been any changes or tweaks  
over the years that would make these locations run less efficiently than  
they could be. As I’m reading this more I’m seeing “If is evil” right?

Location #1:

location ~ /(photos|profile|review|profiles|reviews|news)(/|$) {  
if ($uri ~ ^(._/(photos|profile|review|profiles|reviews|news))($|/._)) {  
rewrite ^(._/(photos|profile|review|profiles|reviews|news))($|/._)  
$1.php?mypath=$3 last;  
}  
}

Location #2:

location ~ ^/galleries(/._$|$) {  
if (-f /usr/local/nginx/htdocs/pixcache$request\_uri/index.html) {  
expires 2h;  
rewrite ^(._)$ /pixcache$1/index.html last;  
break;  
}  
rewrite ^/galleries(/.\*$|$) /galleries.php?mypath=$1 last;  
}

location ~ ^/galleries(?/.\*$|$) {  
expires 2h;

I have an older PCRE with my CentOS version, so am I write in  
remembering the named regex can be changed to from ? to  
?P

Thanks again.

I also wrote it wrong, should be /pixcache$request\_uri/index.html
