It is written in JavaScript asp, I can not read over.
In fact, I do not want to send out, because I boast of too few people.
If you later want to point the classic thinking weird code to boast me a few words.
The purpose of this code is:
do not create a cache wit Html asp file server to save consumption,
the direct use asp to simulate Html cache wit, make the code easier.
Benefits:
1. much better than a simple asp file, open the cache wit, both times without any database queries repeatedly.
2 and change the code easier, Html static dynamic code change once again have to survive all the files.
Disadvantages:
1 static contrast Html files, cache simulation him more steps
but also by the actual static Html IIS cache to execute judgment, but the ASP efficiency is too slow, so this becomes a disadvantage if ASPX then this. points can be ignored
2. when each simulation cache, will go to inquire whether a asp files that have changed, there will be a query IIS, as well as a query component, more than one query default asp.
the only query static files whether a static file changes.
3. each simulation will query the database to get a TimesTamp data.
Modify the code by:
1. Modify the eighth line data connections.
2. Add the database field names for the database field types TimesTamp TimesTamp any field in the database
3. Modify 38.82 row database connection.
