hie dirk,i will make that a practice.

getting back to reverse proxy,when using restxq i some how think it is possible to proxy the web application but not the database server.lets take the following nginx configuration

nginx server configuration :

server {

listen *:80; //nginx server running on port 80.

server_name www.mywebsite.com //port :8080 name of the website/database to proxy.

access_log logs/test.log;

location / {

proxy_pass http://localhost:8080/db/mywebsite.com; //exact location of the site to be proxied

}

Now what my question is that,this configuration works very well for a web application,that is all requests for website "www.mywebsite.com" are passed through the nginx server.

but if i want requests for a db server basex to pass through it how do i specify that.

i mean a web client can access www.mywebsite.com ,but a database client does not access the database directly from a browser....

assuming my basex server is running on port 1984 and the web application is running on port 8000 ,both on same machine.

now the web application opens the connection to port 1984 and sends queries that i want to capture before they hit the database....

And just to let u know,i m following a black box approach,i need to make the implementation code independent.

how can i do it with the described scenario

what can i specify in the server_name header

any help will be highly appreciated.

thanks

Hello Furqan,

please keep in mind to always include the mailing list in the list of

other people might have much better answers than I can give you.

Sure you can use a network sniffer to listen to the traffic to/from a
BaseX server. It is a standard TCP connection, so this is certainly
possible. Just give it a try.

The same holds for using a proxy: It is a very conventional TCP
connection, so using a proxy shouldn't be a problem. Nginx should works
as well, I guess (although I am by no means an expert in nginx). We have
used it quite some times for projects using RestXQ to load-balance
requests. How to actually achieve that heavily depends on the proxy you
decide to use, so you might have to read up there how to do it in detail.

Cheers,
Dirk
