Lg Portable Super Multi Blue Rewriter
James Talbot
This unit come with the Super Multi Blue Advantage! LG Super Multi Blue optical drives can read and write four types of disc formats in one convenient package: 1. DVD+R; 2. RW DVD-R; 3. RW DVD-RAM; 4. Blu-Ray Disc. This gives you the option to choose the media best suited for each task.
The Blu-ray Disc is the next generation in optical storage, offering 25GB and 50GB of storage capacity on a disc, while the BDXL format supports high-capacity blu-ray discs (up to 128GB write-once discs) for users that need to store a large amount of data.
With Serial ATA Technology you get a 1.5Gbps evolutionary replacement for the Parallel ATA physical storage interface used to connect storage devices, such as hard disks, DVD and CD rewriters to the PC motherboard. Serial ATA is scalable, enables design of smaller PCs, and will allow future enhancements to the computing platform. And compared to other recordable DVDs on the market today, M-DISC offers superior reliability in data storage that provides the permanent optical data storage solution.

CSS @import rules each require the browser to fetch the imported file, resulting in multiple round-trips. In line with other filters this one aims to eliminate, or at least reduce, the number of GET requests by the browser, albeit at the expense of increasing the amount of data sent in each response and eliminating possible parallel GETs by the browser (though the rewriter can do the same).
The Css::Parser class will be used to parse the CSS into a Stylesheet instance. Each Import instance from this will be removed then its URL loaded and parsed into another Stylesheet and its elements merged into the top-level one, and so on recursively (as a nested rewriter). The end result will be a single Stylesheet with no Import instances. When the last @import is inlined the Stylesheet will be converted back to text and emitted and the filter will be finished.
If a 404 response is received for an imported file then that file will be ignored but processing will continue. This might not be a good idea because of this statement from the CSS 2.1 2003 specification: User agents may vary in how they handle URIs that designate unavailable or inapplicable resources.
Failed rewrites should be cached as well to avoid repeated doomed attempts at rewriting. The cache life might be [very] short to cater for transient errors. The cache life might be dependent on the actual error - a 404 response could mean a short life while a parse error could mean a long life.
An imported CSS file may start with an @charset rule - it must be the very first thing in the file. If an imported file starts with an @charset rule and the specified character encoding is different from the original encoding, the entire flattening process must be aborted and the original CSS left unchanged; the original encoding will be that of the top-level HTML being processed. If an @charset specifies the same character encoding as is already in use, then the @charset rule will be deleted and processing will continue as described above.
It is possible that the inlining will result in a large single CSS file, making the containing response larger thereby negatively impacting performance - the assumption is that any such impact will be more than offset by the improvement from having a single response. However we will probably have a configuration parameter that limits how big the inlined CSS can be.
We should cache each flattened @import separately in case they are used multiple times (which apparently will happen automatically due to this being a nest rewriter). For example, say we have a.css and b.css and both import c.css - if we cached the flattened version of c.css while processing a.css, it would speed up the flattening of b.css later.
