• HTTP GET: Same GET-Parameter multiple Times, is this allowed by RFCs?

  - by bernhard

  Hello, are all "Standard Compliant (HTTP RFC?)" Web-Servers forced to "somehow" provide some methods to get all Parameters with the same name as some kind of list/array? Or will will using the same parameter name lead to overwriting: Example: http://www.stackoverflow?myparam=value1&myparam=value2 Will this lead to myparam holding the values "value1,value2" or only "value2" (due to overwriting and only using the last one). Is this behaviour mandated by some standard? thanks bernhard

• OK to throw an error for a missing required querystring parameter?

  - by Balazs

  Is there anything wrong with having an asp.net page throw a (custom error) if a a required querystring parameter is missing and having global.asax catch it with Application_Error, then transfer the user to an error page? I have several base classes that perform these checks and I am not sure of the best way to communicate the error to a user. So, something like this: int reqParam; if(!isParamSet("myReqParam", out reqParam)) { throw new QuerystringParamMissingException(); } which is then caught by Application_Error in global.asax.

• Any way to specify a non-positional parameter in a powershell script?

  - by Julian Birch

  I've got the following at the start of a script Param( [string]$command, [string]$version = "1.1.0" ) This is fine, only I need for $version to not be a positional parameter, so that if you type .\script.ps1 run argument Then $args should contain argument and $version should be 1.1.0. Is this even possible? I know I can do it with a c# cmdlet, but it would be massively more convenient if I could deliver this as a single script.
