404 error on nginx location directive - redirect

Question

I am trying to convert my apache redirection directives to nginx one, for now I have the following directive:
server {
listen 80;
index index.php index.html;
server_name myvisit_head;
root /var/www/mv/head/myvisit/;
access_log /var/log/nginx/myvisit-access.log;
error_log /var/log/nginx/myvisit-error.log;
# Use gzip compression
# gzip_static on; # Uncomment if you compiled Nginx using --with-http_gzip_static_module
gzip on;
gzip_disable "msie6";
gzip_vary on;
gzip_proxied any;
gzip_comp_level 5;
gzip_buffers 16 8k;
gzip_http_version 1.0;
gzip_types text/plain text/css application/json application/x-javascript text/xml application/$
# error pages
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /var/www;
}
# Deny access to hidden files
location ~* /\.ht {
deny all;
access_log off;
log_not_found off;
}
location / {
try_files $uri $uri/ /index.php?$args;
}
location ~* /myvisitv3 {
rewrite /(myvisitv3|myvisitV3|myVisitv3|myVisitV3)([-_])(.*).(html|php)$ /myvisitv3.php?libAdresse=$3 break;
}
# Pass PHP scripts on to PHP-FPM
include global/php-fpm.conf;
location ~* \.php$ {
try_files $uri /index.php;
fastcgi_index index.php;
fastcgi_pass php5-fpm-sock;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param SCRIPT_NAME $fastcgi_script_name;
fastcgi_param PHP_VALUE "auto_prepend_file=/var/www/profile/external/header.php \n
auto_append_file=/var/www/profile/external/footer.php";
include /etc/nginx/fastcgi_params;
}
}
but when I try to access the url I get a 404 not found error.
I have tried both with location, request_uri directive but the result is the same
here's my apache rules:
RewriteEngine on
RewriteRule ^(myvisitv3|myvisitV3|myVisitv3|myVisitV3)([-_])(.*).(html|php)$ myvisitv3.php?libAdresse=$3 [L,QSA]
RewriteRule ^(openVisit|openvisit).(html|php)$ openvisitv3.php [L,QSA]
RewriteRule ^(favicon).(ico|png|bmp|jpg)$ web/img/favicon.ico [L,QSA]

Answer 1

These rules use case insensitive matching to spare us the hassle of handling those so many cases.
location ~* /myvisitv3[-_](.*)\.(?:html|php) {
try_files $uri $uri/ /myvisitv3.php?libAdresse=$1;
}
location ~* /openvisit\.(?:html|php)$ {
try_files $uri $uri/ /openvisitv3.php;
}
location ~* /favicon\.(?:ico|png|bmp|jpg)$ {
try_files $uri $uri/ /web/img/favicon.ico;
}
