httpRequest.que rystring

[Mark]

Hello
Can anyone tell me how to check if a a querystring is present or not

I.E. If request.queryst ring("key") is in the url or not

because when i try to reference it in anyway and its not there I get an
error there has to be an easier way then having to put all the checks in a
try catch statement
Thanks

If request.queryst ring("key") is nothing then
Or
If Not request.queryst ring("key") is nothing then
or if the key exists but has no value set
try
if not request.queryst ring("key").toS tring.trim.leng th then
DOntdothis()
end if
' this always throws an exception with a null value or of course you can jus
return dothis()
Catch ex as exception
return Dontdothis()
end try

Actually you hit on the simplest way to do it, if you need to tell the user
what is wrong this also works great with a custom validator.
try
catch ex as exception
finally
end try
Put the code to handle things without the proper key into catch.
