Hi,
In the wiki for the map module (Module ngx_http_map_module)
the
following is given as an example:
map $uri $myvalue {
/aa /mapped_aa;
~^/aa/(?.*)$ /mapped_bb/$suffix;
}
The second form, the regex, I can’t get to work - it returns the literal
text
rather than substituting for $suffix.
from my map block:
map $uri $locn {
~^/pdns(?.*)$ /var/www/pdns$suffix;
}
the I rewrite:
rewrite ^ $locn;
from the log:
open() “/var/www/pdns$suffix” failed
How do I get this to substitute?
This is using nginx/1.1.0 on debian squeeze.

Wiki is wrong here. Currently nginx does not support expression
in value part, you may use only a single variable, i.e.:
~^/pdns(?.*)$ $suffix;
However, this wiki example is very ineffectual, because it maps $uri to
path
forcing to use “rewrite”. There are other simple ways to this, for
example:
location /pdns {
root /var/www;
}
or (wiki expample):
location = /aa {
alias /mapped_aa;
}
location /aa/ {
alias /mapped_bb/;
}

I thought that might be it 
What I’m trying to do is make my config file more elegant. I have quite
a
number of subdirectories which all have their own document root. So
there’s a
location for each and each has to have an alias and a php proxy. I was
trying
to coalesce them.
So I tried:
map $uri $locn {
/sub1 /locn1;
/sub2 /locn2;
...
}
index index.php;
location ~ ^/(sub1|sub2 etc ) {
alias $locn;
location ~ .php$ {
}
}
but it doesn’t work. fastcgi can’t find the file. One symptom is that
$request_filename is not set to the full path; i.e the index.php part is
missing.
It works OK if I put a literal in the alias rather than the same value
from a
mapped variable.
Is this construct supported?
There’s another problem I don’t understand
If I have
index index.php;
location /sub1 {
alias /path1;
…
}
It looks for /path1/index.php as expected but if I change location to
regex
location ~ ^/sub1
then it looks for /path1 with no index.
