HI guys. I am trying to make something to work in nginx but I have no  
luck.  
I posted in StackOverflow, and no answer.  
I wish any of you can help me. I paste the SO question here as well:

I am using nginx and I need a proxy to redirect some service. From my  
application, I should be able to do a POST, for example, to this URL:  
[http://localhost:8776/specialService/aserverthatlistens.com/serviceToCall](http://localhost:8776/specialService/aserverthatlistens.com/serviceToCall).  
And I need to rewrite it like this:  
[https://aserverthatlistens.com/serviceToCall](https://aserverthatlistens.com/serviceToCall) (notice that this URL is  
HTTPS,  
not HTTP).

I know I can use rewrite but I don’t know how to use proxy\_pass also,  
because the url of the proxy\_pass should be what I rewrote…

Notice that I cannot know in advance what is the final url  
([aserverthatlistens.com](http://aserverthatlistens.com) in this example), so I always need to get it  
form  
the URL. I could send it as parameter if that help instead of being part  
of  
the URL.

So far my server configuration looks like this:

server  
{  
listen 8776;  
server\_name localhost;

access\_log /var/log/nginx/tunnel.log;  
error\_log /var/log/nginx/error.log info;

location ~ ^/someService(/.\*)$ {  
proxy\_pass https://$1;

}

}

What does the error log say?

What does the error log say when you change proxy\_pass to have 2 slashes  
and not 3?
