Subject: Fisher's Exact Test vs Generalized Linear Models

I have a binary response variable as the results of a simple designed
experiment. The experiment could be either a one-factor experiment
with k levels of the independent variable, or it might be a two-factor
experiment with k1 and k2 levels of the independent variables.
In either case, I can run Fisher's exact test or I can fit a
generalized linear model. In SAS, you would use PROC FREQ for Fisher's
exact test, or you can fit the generalized linear model with PROC
Fisher's exact test and the generalized linear model test do not seem
to give the same results when you test to see if the factor(s) have an
I am hoping someone can explains the pros and cons of each test, or
point me to a reference.
