  1. Only some directives are allowed inside “if” block.

  2. If you have two or more “if” blocks and their conditions are true,
    then
    only last block configuration will be used, they are not merged as
    one
    may expect:

    if (true) {
    configuration A
    }

    if (true again) {
    configuration B # only this configuration will be used
    }

Our entire setup is built around these right now.

Could you show example of the setup ?

No, they does not impact the perfomance, but they has many limits

However, this does not apply to ngx_http_directive: rewrite, return, and
set:
they will be executed in both configuration: A an B. And this may
confuse too.

there is a good bit of cruft in this as it has built up over 18 months
and was started when i knew basically zip about nginx.
its also very site specific ( our software does amusing things with
urls… ), kind of the uri equivalent of how i abused strings
in the if statements below to simulate ‘and’ for nginx if.

that said, here are the important parts… as noted, its all built
around if statements… largely because
this all is already inside location blocks ( i can provide more
context if you need. )

set $dynamic 0;
set $handler “lp”;
set $real_file $request_filename;

if ( $uri ~* ^/s-([^/])/(.)$ )
{
set $has_lid 1;
set $lid $1;
set $handler $2;
set $real_file $document_root/$handler;
}

dynamics

if ( !-e $real_file )
{
set $dynamic 1;
}

if ( -e $real_file/index.i )
{
set $dynamic 1;
}

if ( $real_file ~* .(i|pl)$ )
{
set $dynamic 1;
}

next 6 lines required if no site has setup any geotargeting

if ( $geotarget = 0 )
{
set $geotarget 0;
set $geotarget_domain 0;
set $geotarget_lid 0;
}
set $dyn_geo “$dynamic:$geotarget”;
if ( $dyn_geo = ‘1:1’ )
{
rewrite (.*) http://micro.$geotarget_domain/s-
$geotarget_lid&subid=$lid/$handler redirect;
break;
}

if ( $dynamic )
{
error_page 404 = @memcache;
break;
}

if ( $has_lid )
{
rewrite ^(/s-[^/]/)(.)$ /$2;
}

Your configuration is good in general.
The set’s are intended for use in “if”.
