hiding the identity of nginx

[huet bartels]

Dear All.

Have managed to check the following files to change the identity of
nginx to another string, plus the footer section of the error pages.

This seems to of work for the most part by changing the following files.

src/http/ngx_http_header_filter_module.c
src/http/ngx_http_special_response.c

But when I looked at the headers via firefox the images where still
showing nginx as the server.  Where else would I need to change this in
the source to completely hide the string nginx from the public

thank you in advance
