Man I can't believe this. I'm still mucking around with OFX servers and it drives me absolutely crazy how some these servers are just so unbelievably misconfigured.

If anyone can help it would be appreciated. I would like to enable compression for static files within IIS7 (for the sake of simplicity I'll just refer to static css files for the time being).
The problem I'm getting is that css files are only compressed when both dynamic and static compression…

IIS 7 also supports dynamic compression which allows automatic compression of content created in your own applications (ASP…

I was thinking of turning this on some large databases not just mail files - we have around 8 - 10GB of large databases as well as small databases of couple of hundred MB in size.

I need to choose a compression algorithm to compress some data. I don't know the type of data I'll be compressing in advance (think of it as kinda like the WinRAR program).
