Dude! You are going to absolutely freak out when you see what we are working on for the next version. Even that old lady on the bus is going to be talking about it! I'm bursting to give the details but can't. We'll probably have something public this fall.

I've been thinking along exactly the same lines :)

Same here! Would be great to have PowerShell as dynamic language for web site development. All this power at your fingertips... Rally looknig forward on what you are working on Jeffrey, any possibilities to get is the beta program for that?

even brucey's sample web-server is very dangerous -- it's open to 'powershell injection!'

i just used it to create a directory on my machine (an example of a dangerous side effect... lucky i didn't try delete...)

i passed this to it:

http://127.0.0.1/get-date;dir;md f;1*5

and it executed all the commands (not just the 1*5)....

to fix this i changed the line with regular expression in it from:

if ($expression -match '[0-9.]+ *[-+*/%] *[0-9.]+')

to:

if ($expression.trim() -match '^[0-9.]+ *[-+*/%] *[0-9.]+$')

(three changes: added the trim(), added a ^ to the front of the regex, added a '$' to the end of the regex.)

much safer ;-)

Is this JAP (Just Another Perl) ?

And look what crimes against humanity people are doing with Perl...

Very cool. I attended a Powershell ISV training event in Redmond a few weeks ago, and now I'm reading Bruce's book. I am actually getting more and more psyched about Powershell, and am seriously considering working on adapting Powershell to the web. I'd probably focus on IIS though, as that's make it easier to host the app at a web hosting service.

BTW, why do you call the SoapyFrog example "dangerous?"

'lb' on Wed, 02 May 2007 22:37:18 GMT, sez:

@Mike
soapy frog's example is potentially dangerous because if you posted it up on a public-facing internet site, then anyone could come along and use it to run a command such as Delete *.* on your server.

regarding "adapting Powershell to the web" i'm waiting to see what the powershell do next -- because i think they're gonna do the hard work for us.

Ah...Doh! For some reason I asked that after reading several others and I got it confused with [1]. What do you think of [1] as a framework for calling "Powershell Server Pages" using the Powershell SDK? Would it scale? Bart wrote "Ignore the naive approach to threading in Main" but he's turned off comments so I can't easily ask him what he means.

And from your comments on [2]:

lb> i think that the powershell team are doing some tricky stuff
lb> for the next release to let powershell be webified more easily.

I asked Jeffrey when I was in Redmond a few weeks ago and he said it would be nice if someone did something Powershell for the web but they were instead focused on system managability for several years. :-(

lb> they ought to be involved in the DLR -- but weren't mentioned
lb> there as far as i could see.

DLR?
