I’ve noticed imitative behaviors in all of my fish, including goldfish, parrot cichlids, convict cichlids, severums and oscars. Although they come out of the egg already knowing how to swim, how to eat, and how to hide, they add new behaviors as they grow.
Learning attitude: Parrot Cichlids
When young parrot cichlids are put in a tank by themselves, they will usually remain shy for weeks or months. They will hide behind anything they can. If there is nowhere else to hide, they will hover at the top corner of the tank tipping downward slightly, pretending to be part of the filter. However, if they are put into a tank with adult parrot cichlids who have no fear of humans, they get over their shyness very quickly! When we got one of our younger parrots, “Baby,” she immediately adopted the oldest parrot cichlid Winston (a female) as her “mother.” She would follow Winston around, and generally imitate everything she did, and as a result showed very little fear of us.
But most of our newly acquired parrot cichlids spend at least a day or two hiding, during which they peek out from a secure spot to observe what’s going on in the tank.

Suppose you want server-side includes to be processed in .htm files also? For example you may have file with the .htm extension which has been on the web for some time and has numerous links pointing at it. You could replace it with a file with one of the allowed extensions, and put a redirect in its place, pointing to the new file. Or, if you have access to the IIS server settings, you could add the .htm extension to the list of files processed for SSI.

Sometimes it is necessary to have files or an application on one IIS web server (Server B) appear as if they were in the same domain as another server (Server A). For example, you may want
http://serverB.com/content
to be accessible via the URL
http://serverA.com/content
This is useful in cases where you need to avoid cross-doman scripting issues, or simply want to make everything appear to be hosted under one umbrella domain name.
On an IIS server, this can be accomplished by creating a virtual directory on Server A which points to a directory on Server B.

Here are the steps involved:
During our recent Docent LMS implementation, one of the most difficult tasks I was faced with was to ensure SCORM activities work if browsers other than IE were used.
The specific cross-platform issues fell into several categories:
