C socket redirection


C socket redirection

I wish this help you I don't know about any efficient way to do this without a buffer, so here is an example without using separate threads and only one buffer. You could use the doRW function below from multiple threads, but only with one buffer per thread. Recv and send seem to be thread safe methods as discussed in "Are parallel calls to send/recv on the same socket valid?".
code :
int fd_a, fd_b;

void fd_init()
{
    fd_a = socket(AF_INET, SOCK_STREAM, 0);
    fd_b = socket(AF_INET, SOCK_STREAM, 0); 
}
bool doRW(int a, int b, char* buf, int size){
    int len = recv(a, buf, size, 0);
    if(len == 0) return false; //disconnected
    else if(len > 0) send(b, buf, len, 0);
    return true;
}
int main(int argc, char* argv[])
{
    // ...
    fd_init();
    fcntl(fd_a, F_SETFL, O_NONBLOCK);
    fcntl(fd_b, F_SETFL, O_NONBLOCK);
    char* buf = malloc(2048);
    while(doRW(fd_a, fd_b, buf, 2048) && doRW(fd_b, fd_a, buf, 2048)) ;
    free(buf);
    return EXIT_SUCCESS;
}

I hope this helps . I'm struggling to understand command redirection/reuse... , In reply to your comment:
code :
sort <(cd $CURR_DIR && find . -type f -ctime $FTIME) \ 
    <(cd $CURR_DIR && find . -type f -atime $FTIME) \ 
    <(cd $CURR_DIR && find . -type f -mtime $FTIME) | uniq
(find . -type f -ctime $FTIME && find . -type f -atime $FTIME \
    && find . -type f -mtime $FTIME) | sort | uniq
mkfifo named_pipe{1,2,3}; (echo z ; echo a ; echo z) > named_pipe1 & \
    tee < named_pipe1 >(sort > named_pipe2) | sort | uniq > named_pipe3 & \
    output=$(echo sorted `cat named_pipe2`; echo unique `cat named_pipe3`); \
    rm named_pipe{1,2,3}

I wish this help you I have redirection URL like "https://www.syncfusion.com/msdn" . if we entered this URL in browser, it goes to "https://www.syncfusion.com/home/aboutus?utm_medium=msdn". , In the controller itself you can do the same.
code :
   return  RedirectToAction("Redirection", "root",new{key="msdn"})
return Redirect(redirecturl)

like below fixes the issue
$_SERVER['HTTPS'] is always empty, but $_SERVER['HTTP_X_FORWARDED_PROTO'] returns https when I am on https page
code :
# www to non-www redirect
RewriteCond %{HTTP_HOST} !^example\.com
RewriteRule (.*) https://example.com/$1 [R=301,L]

# http to https redirect
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
# Canonical redirect (no-www and HTTPS)
RewriteCond %{HTTP_HOST} !^example\.com [OR]
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule (.*) https://example.com/$1 [R=301,L]

I think the issue was by ths following , A 64-bit version of Windows already has all the features in place to make it unnecessary for you to take care of it yourself. You just need to keep the rules in mind when you troubleshoot problems.
First is the registry redirector, it ensures that a 32-bit client program cannot accidentally read keys that contain configuration information that's only appropriate for 64-bit programs. You already know it, most of the HKLM\Software registry accesses are redirected to HKLM\Software\Wow6432Node. This redirection is already in place when the COM server is registered, a 32-bit installer is automatically redirected to write the keys to Wow6432Node instead. The installer is completely unaware that Wow6432Node even exists. Everything falls together automatically, the installer is redirected and the COM server client is redirected as well. All that you care about is knowing where to look to verify that the install was done properly, you do have to look at HKLM\Software\Wow6432Node\Classes\CLSID with Regedit.exe to find the keys back.
