Note that any time you build a query as a string if you allow users to insert parameter values or control the string you are building in any way into you need to be aware of SQL injection attacks. This is not a problem with '?' query argument substitution as it is designed to avoid injection attacks, but if you have say:

Set sql="select Name from MyTable where Age > "_userage

And the user supplies 'userage' then they could provide "100; drop table MyTable;" or worse.

In Cache 2017.1 we have light weight SQL profiling enabled by default which will keep track of the number of times each SQL query is called and how long these queries take.  So you can quickly answer the question as to which SQL queries matter to your application and then investigate these important queries in more detail.

This information will show up in the system management portal in the SQL explorer section under the sql queries in this namespace section.

Note that NIST has come up with new recommendations about password security, here is a good overview:

Specifically see this section:

No composition rules. What this means is, no more rules that force you to use particular characters or combinations, like those daunting conditions on some password reset pages that say, “Your password must contain one lowercase letter, one uppercase letter, one number, four symbols but not &%#@_, and the surname of at least one astronaut.”

So it recommends against complex patterns such as the one you are asking about. Also of interest is this one:

No more expiration without reason. This is my favourite piece of advice: If we want users to comply and choose long, hard-to-guess passwords, we shouldn’t make them change those passwords unnecessarily.

The only time passwords should be reset is when they are forgotten, if they have been phished, or if you think (or know) that your password database has been stolen and could therefore be subjected to an offline brute-force attack.

Some tools do not like the fact that the RSS feed is badly formatted as there are no title fields, this was reported a long time ago but is still not fixed for example the start of '':

<?xml version="1.0" encoding="utf-8" ?><rss version="2.0" xml:base="" xmlns:dc="" xmlns:atom="" xmlns:content="" xmlns:foaf="" xmlns:og="" xmlns:rdfs="" xmlns:sioc="" xmlns:sioct="" xmlns:skos="" xmlns:xsd="">

The 'Do While' is in fact identical to the 'For' block structure except it adds a redundant while condition at the end which is never false as it will have already exited this block from the 'Quit:Sub1=""' condition earlier, so you should probably remove this as it just takes the 'For' structure and adds this extra test which will slow the loop down.

A disadvantage of the 'While' structure is first you need to repeat the iteration construct, e.g. 'Set Sub1=$O(^Trans(Sub1))' before entering the loop and at the end. Also if you need to skip an item with say the 'For' structure you can just issue a 'Continue' but with the 'While' structure you have to advance the current subscript value manually before issuing a 'Continue'

In the 'Method Levels' the lines like 'Goto Level1' are not needed as the previous line says 'Set Sub2="" Goto Level2' so it will always be evaluating this 'Goto Level2' and so will never get to the next line. Rather than having this you can simplify to just 'Set Sub2=""' and remove both 'Goto' statements so it will just drop down into Level2 automatically.

Why do you want the connection id to change? In CSP we route multiple requests to a few server processes to be able to handle massive numbers of client efficiently. However the process that handles the request does not hold any information about the session at all, all this information such as the license we hold is in the %session object so as long as you have a new %session object this is a brand new connection.
