No, that is not common, but there are many different shower pans, so mistakes are possible.
I can consider it to be both.
Liner is basically a kind of casing the main difference b/w liner and ordinary casing is that , the ordinary casing extends from surface to particular depth but in case of liner it does not extend from surface to particular depth but it attaches with the last part of the above casing .For example if you have drilled TD of 15000 ft and you have to install a liner at the bottom and suppose the liner length is 200ft.All the other casings will be installed from surface to to its particular desire depth but liner will be installed at the bottom of the other casings . Advantages 1.Economics: you save the cost of 14800 ft of steel or aluminum . 2.Reducing the pressure at the surface: If you install a liner having a length of 15000 ft it will produce a lot of pressure on the surface .
The item used under the shower pan to create the slope for the drain is called a "shower pan liner" or "shower pan membrane". It is typically made of PVC or CPE (chlorinated polyethylene) and is installed over the subfloor and around the drain to create a waterproof barrier. The liner is then sloped towards the drain using a combination of techniques, such as sand or mortar beds, pre-sloped foam panels, or adjustable slope systems. The choice of method depends on the specific requirements of the installation and the installer's preference. Once the liner is in place and sloped properly, the shower pan can be installed on top of it, and the tile or other finish material can be applied. Proper installation of the shower pan liner is crucial for ensuring that water drains properly and does not seep into the subfloor or surrounding areas, causing damage or mold growth. HydroBlok systems are known for their durability, water resistance, and ease of installation. They can be used for both residential and commercial applications and are suitable for a variety of finishes, including tile, stone, and vinyl.
Anti-polishing rings are used to prevent carbon build-up in the cylinder liner. The carbon polishes the cylinder liner leaving it with a smooth surface. A smooth cylinder liner is bad because the lube oil won't be able to stick to the liner.
A flue liner protects the bricks or masonry that makes your chimney for your fireplace. It can also protect any wood that it is close to. Flex King offers a flue liner for around $400.00.

a shower curtain goes on the outside and a shower liner goes on the inside so the shower curtain wont get wet
The best way is to install 6 mil or greater poly sheeting. this will ensure a longer lasting seal.
A shower curtain is for decor and hung on the outside of the bathtub/shower. Whereas a shower curtain liner is hung on the inside of the tub/shower to protect the shower curtain. In simpler terms...SHOWER CURTAIN: gets to hang and look pretty and be dry. SHOWER CURTAIN LINER: protects shower curtain from getting wet because it's the one getting wet!
Yes
Curtain in, liner out.

I would use a white mildew resistant shower curtain liner behing the Ruffles shower curtain.
A shower curtain liner made of vinyl or nylon and that is machine washable and bleach tolerant is the best choice. Ecopreme is a new chlorine free, environmentally friendly shower curtain. The best selection I have seen is at www.shower-curtains.com
