Using map module variable being unset with if

Server NGINX
#1

Hey guys,

I have been trying to use the nginx map module to do some rewrites in
bulk, basically my
map looks something like this:

map $request_body $var {
default no;
~.+.string1 dorw;
~.+.string2 dorw;
…
}

in a location i have the following

if ($var = dorw){
rewrite ^ /home last;
}

I also have a log_format which logs the variable state (and it reports
correct), however
once I enable that if… the $var seems to reset to ‘no’.

Any ideas? This is kind of confusing.

Thanks and any help is much appreciated.

Lou

$request_body isn’t available unless it’s read, and this happens
after rewrite phase where “if” is executed. Therefore testing
$var with “if” will always result in “no” and this result will be
cached for further use.

Thanks Maxim.

Any other way I can accomplish this using the map above? Thanks

Also, is there any variable in Nginx that will hold the original URL
(including anchors, like /foo/bar/#get/this/that)?

Thanks

Browsers do not send anchors (fragments) in their requests to the
server.
