arsd.cgi - maximum length of form post

[bachmeier via Digitalmars-d-learn]

I'm using arsd.cgi, and have a form set up to take input. I get a 
range violation error core.exception.RangeError@test.d(109): 
Range violation when using the embedded server. It appears to be 
because the input is too large (about 3900 characters). When I 
cut the input to 3000 characters, there is no error.

Is there a way to increase the maximum post size?
