Probably not. fstab isn't magic, it's just a list of file systems that your computer will try to mount at start time (and other times, but start time is usually where it's read). The file is read, and then various mount utilities are used, depending on the file system type. And CIFS as a protocol isn't remotely close to the http protocol. It's like you're writing 'plug the Nintendo 64 cartridge into the XBox360' and assuming it will just work. You need something that actually speaks http in this instance.
Do you really need file system over http, or do you want to just read/write files on a webserver that you control? If it's the latter, you need to figure out how those files are served on a fileserver (cifs, nfs) and configure that.
Do you really want to serve over http? It wasn't designed (though can be forced into it) as a file system protocol. Look into WebDav, and there are some (http://savannah.nongnu.org/projects/davfs2) true drivers for webdav.
