-# Multi cgi test
-
-Test to check the non blocking behavior of the server when multiple cgi request (which takes a certain time to be executed) are send to the server.
-
-In the development site (www.development) in the cgi-bin folder we have a duration.sh script that send three curl requests to the duration.cgi script, which is a python script. The scripts log the start time and the end time of the cgi and in between the script sleep some seconds.
-The script then analyse the times on the responses and print out the results. To serve the development site we will use the development.conf file.
