Nginx/apache/iis pseudo-static writing and Difference

For work reasons, I want to write a pseudo-static file as an instance nginx apache iis cache. Here we will separate my instances.

Apache pseudo-static writing

Rewriteengine on
Rewriterule/rss/(. *). xml $/rss. php tutorial? A = $1
Rewriterule/xml/(. *). xml $/xml. php? A = $1

Iis pseudo-static writing

Rewriterule/rss/(. *). xml $/rss. php? A = $1 [n, I]
Rewriterule/xml/(. *). xml $/xml. php? A = $1 [n, I]

Nginx pseudo-static writing

Rewrite ^/rss/(. *). xml $/rss. php? A = $1 last;
Rewrite ^/xml/(. *). xml $/xml. php? A = $1 last;

Summary of the differences between the three

See the above three instances. For nginx/apache/iis pseudo-static writing, apache and iis add [n, i] But the difference between iis and nginx pseudo-static writing is that the start ^ and end with a last. In a word, they are too minor.
