Re: NKE tcp redirect socket filter 10.4+

It is possible but it is tricky to get right. I wrote a sample to test the KPI and did get it working but I can't find it now.

DTS should be able to help. There should be archives that go over the basics but gloss over the details.

I need to intercept in NKE, brower requests to

a certain host name and redirect it to another. (it eventually should get back to the browser)

I am looking into "socket filter" but so far with no success.

I am trying in "tl_connect_out_fn(void *cookie, socket_t so, const struct sockaddr *to)" to manipulate the host

Does the below extraction claim it's possible?

#==================================

Note: If you were considering calling sock_close to redirect a socket to a different location, 

you can do this by intercepting the connection request with a socket filter and redirecting the stream when the application first opens the socket. 

Once opened, however, a stream cannot be redirected. For more information, see “Socket filters.”
