Description
I am capturing some data in if, and then redirecting on what was captured. The problem is, that captured data is escaped if url contains "%" char, and may be others, and do not escaped if it does not. I have simple config:
Having simple config
location / {
set $out "http://example.com/?a=b&c=d%";
if ( $out ~ "(.*)" ){
set $z $1;
rewrite $z redirect;
}
Making 2 requests:
telnet 127.0.0.1 80
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is ']'.
