Does PHP have a feature to associate Cookie sessions with a persistent
database connection that will allow a single transaction across
multiple HTTP requests?
Here is how I imagine my process: I have an series of interactive HTML
forms. The user begins a Cookie session. A database connection is
opened and a transaction is begun. After the user goes through any
number of pages where they update the database they finish on a page

It seems, it is caching it.
The following code is an example for it. How can avoid from this.
override void OnLoad (sender and eventargs)
{
Control control = this.LoadControl (path);
this.Controls.Add (control);
// I change the content of the html of the control.
TextReader reader = new StreamReader (path);

application, when in the session object, data is fine, however as there is
only one instance of the class files, when data is put into them,...

I'm retrieving some columns from a database with numeric values that
fall comfortably within the range of the Single type and I'm tempted
to use Single for the relevant column type in the retrieved dataset.
(Actually the values are held as integers in the database for compact
storage but are scaled to their true Single values during retrieval).
But I'm sure that I keep reading that there's no performance penalty
to using Double rather...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp

I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
