Storing URI in a cookie

Server NGINX
1

I dont know why I am struggling with this so much but I need a bit of
help.
I am trying to redirect users to a verification page and then back to
their
original requested URI but because of the rewrite I lose both the $uri
and
$request_uri variables. I figure the easiest way to solve this problem
is
to store the original URI in a cookie and read it from that after the
verification page. I cant seem to store the cookie correctly and read
it
back. Can anyone provide some direction? Also, is there any risk that
by
doing this I disrupt other cookies being stored by my application?

Thanks!

may try this:
add_header Set-Cookie “uri=$uri; path=/”;

A better way to redirect users is to store the uri in the redirection
url.
Storing it in a cookie causes problems if user opens two different tabs
with
two different uris for example.

Thanks guys for the suggestions.

@calin - I have tried doing that but it messes with the verification
page
and am not sure how to implement it correctly.

@Magicbear - I have put that code in there before the rewrite but then
after
the rewrite when I try to access that cookie it is not there. I should
have
been a little more clear on what I have tried and my config. Here is
the
flow of the rewirte.

location / {
error_page 503 = @recaptcha;
if ($verifyvariable)
{
return 503;
}
}

    location @recaptcha {

        add_header Set-Cookie  "originrequest=$request_uri path=/

expires=2m";
secure_cookie
$cookie_CAPTCHA_SESSION,$cookie_CAPTCHA_EXPIRES;
rewrite ^ /captcha.html redirect;
}

location = /captcha.html {
#this has a form that submits information and goes to
/verify
}

location = /verify {
eval_inherit_body on;
eval_override_content_type ‘text/plain’;

eval $verify_content {
proxy_method POST;
proxy_set_header Accept-Encoding “”;
proxy_set_body ;
rewrite .* /recaptcha/api/verify break;
proxy_pass ‘http://www.google.com’;
}

if ($verify_content ~* ^true[\s\R](.)) {
set $error_code $1;
rewrite .* /set_secure_cookie last;
}

}

location = /set_secure_cookie {
internal;

SETTING

rewrite ^ /$cookie_ originrequest redirect;
}
