followup to question about $_POST

[Chris Cortese]

I found this thread: http://www.ruby-forum.com/topic/162377
So, apparently, using the error page to reroute /mycontroller/mymethod 
URLs, does not forward the $_POST array.

I don't really understand how to use the patch, and I wonder if the 
patch is still recommended?  Since it was from last August...

/mycontroller/mymethod is very common across many PHP MVC frameworks.  
Is using the "error" directive really the appropriate way to do this?  I 
tried going back to:

location / {
    if ($request_filename !~ (js|css|images|robots\.txt|index\.php.*) ) {
      rewrite ^/(.*)$ /index.php/$1 last;
    }
}

also tried
location / {
    if ($request_filename !~ (js|css|images|robots\.txt|index\.php.*) ) {
      rewrite ^/(.*)$ /index.php?q=$1 last;
    }
}
both of these methods are recommended on CodeIgniter forums, and I had 
them working previously with nginx 0.6.33

...and now I get 404...
