Hello,
I am using nginx/1.16.1 on CentOS Linux 7. I am using map directive for
managing a large number of redirects from one server to another server :
map $request_uri $new_uri {
include /etc/nginx/conf/redirect.map;
include /etc/nginx/conf/documentation.map;
}
In /etc/nginx/conf/documentation.map, I have 1200 redirections like those
below (the first one works, the second one doesn't).
'/Documentation/Security.html#External'
'https://support.communigate.com/en/guides/communigate-pro-manual/system-administration/security-2/external-authentication';
'/Documentation/Helpers.html#AppHelpers'
'https://support.communigate.com/en/guides/communigate-pro-manual/applications/helper-applications/external-application-helpers;'
If I try to use
https://communigate.com/documentation/Helpers.html#AppHelpers (first
redirection), I have "page not found (404)" and the logs are :
162.158.50.134 - - [12/Apr/2022:07:48:17 +0000] "GET
/documentation//Helpers.html HTTP/2.0" 301 0 "-" "Mozilla/5.0 (X11; Linux
x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/100.0.4896.75
Safari/537.36"
162.158.50.134 - - [12/Apr/2022:07:48:17 +0000] "GET

x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/100.0.4896.75
Safari/537.36"
If I try to use
https://communigate.com/documentation//Security.html#External (second
redirection), I have the page and the logs are :
141.101.68.139 - - [12/Apr/2022:07:50:26 +0000] "GET
/documentation//Security.html HTTP/2.0" 301 0 "-" "Mozilla/5.0 (X11; Linux

x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/100.0.4896.75
Safari/537.36"
If I try to access from my nginx server to the destination URL
https://support.communigate.com/en/guides/communigate-pro-manual/system-administration/security-2/external-authentication
or
I have tested there is no synthax error in my configuration file with :
# nginx -c /etc/nginx/nginx.conf -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
I also tried systemctl reload/restart nginx without results.
Do you know how can I debug that ? Is there a way to check what are the
requests done to destination host by my nginx server ?
Thanks in advance for your help.
Gilles
