I want sessions and cookies to hold! 回答1: Has nothing to do with Express. It's the settings on the cookie itself that matter. Set its domain to .mydomain.com and you should be fine. EDIT : The OP wanted more details, so here are the examples from the code. connect.createServer( connect.cookieParser() , connect.session({ cookie: { domain : ".mydomain.com" }}) ); and res.cookie('remember', 1, { domain : ".mydomain.com" }); should work. 文章来源: How do I

Unfortunately, I'm running PHP on a Linux server and using dblib to interface with Microsoft SQL Server, which doesn't support PDO::lastInsertID() . Please help!

Then, using the mouse, I rotate it some way. Now I run the command again, expecting to obtain the original shape (i.e the original orientation before I rotated it by mouse), but instead, it just gives me the same plot I have on the screen, i.e. it seems to have kept/remembered the last viewpoint in that output cell. I wanted it to go back to the original viewpoint. So, I delete the output cell to make it happen. Do you think this is how

From the exact same reason, which is no reason at all, I also implemented it in C#. My question is: Do you see any mistake in my algorithm or code? And, more importantly, can you suggest a better algorithm? Please pay more attention to the algorithm than the code itself. It's not the prettiest code I've ever written, although do

This array represents consecutive operations: if A[K] = X, such that 1 ≤ X ≤ N, then operation K is increase(X), if A[K] = N + 1 then operation K is max_counter. For example, given integer N = 5 and array A such that: A[0] = 3 A[1] = 4 A[2] = 4 A[3] = 6 A[4] = 1 A[5] = 4 A[6] = 4 the values of the counters after each consecutive operation will be: (0, 0, 1, 0, 0) (0
