I'm configuring nginx as reverse proxy.
I need to change (rewrite?) the URLs, example: when the request (to nginx Reverse Proxy) is "http://example.com/test/?username=test1;password=passwdtest1" it will must "modified" to the main server as "http://example.com/test/?username=production;password=passwdproduction1".
Consider that in the original request the fields "username=test1;password=passwdtest1" are not always the same (they changes), instead the "modified" to the main server are always the same.
Others example to be more clear:
"/test/?username=test1;password=passwdtest1" -> "/test/?username=production;password=passwdproduction1"
"/test/?username=test1876;password=somepasswd" -> "/test/?username=production;password=passwdproduction1"
"/test/?username=somevalues;password=somepasswdvalue" -> "/test/?username=production;password=passwdproduction1"
So, independently to what are the values of "?username=somevalues;password=somepasswdvalue" it should always become "?username=production;password=passwdproduction1".
Thanks for your help!
