Hi,

I really need the same for rewrite and variables like $http_referer or $request_uri.

There were several questions regarding that in the past, but I can't find a solution.

An example:
[code]
# url rewriting
location ~ \.htm$ {
rewrite ^/([a-z0-9_]+)\.htm$ /$1.php?uri=$request_uri break;
proxy_next_upstream error timeout http_500 http_503 http_404 invalid_header;
proxy_pass http://backend;
}
[/code]

In some rules $request_uri contains arguments with ampersand and as it isn't escaped, those won't be part of the "uri"-var.

I really like to have a function like url_encode() or something similar to str_replace().

regards,
Marc
