Perl on IIS 4

This FAQ is mainly about issues arising from using Perl on IIS4. It strays into other territory occasionally.

I don't really update these pages any more, as you can see by the date just below. There are several reasons for this:

  1. First and foremost, I now work for someone else, in a different capacity. Instead of web server interfaces in Perl, I'm writing compiler optimisers in C. Therefore, my job no longer entails working with IIS. I'm quite pleased with this.
  2. Since I don't have IIS at home (heck, this is on Linux), I no longer have access to an IIS server. That means I'm now relying on memory...
  3. I don't read the IIS newgroups any more. For the above two reasons.
  4. Finally, I'd guess that the IIS world should have moved on by now. I mean, it's been several years, folks. How many of you are still using IIS3/4? (that's a rhetorical question; I'm not conducting a survey here).

Please consider the disclaimer, consider the poor folks who sweated blood for this, and if you're thinking of asking for help, please see if you can help yourself first.

Disclaimers

I don't take any responsibility for the accuracy of the information in this document; I'm just collecting personal experience and comments from the net, so use at your own risk. Given that some of the people listed posted advice to the net, rather than to me directly, some of them don't even know their pearls are listed here, so you definitely can't blame them.

Basically, if there's something wrong, (a) sorry, and (b) please let me know, so that I can correct it. 'Course, given how often I've updated recently, the latter may never happen.
