Dynamic Parameters as recognized by Site Explorer can be defined in the following steps:

1. Take the initial part of the URL up to the first occurrence of ';', '?' or '&' as the static part of the URL
2. Segment the rest of the URL by each ';', '?'. '&' that occurs
3. Within each of the segments thus produced:
1. if the string looks like 'a=b', then 'a' is the parameter name and 'b' is the parameter value
2. if the string looks like 'a', then 'a' is the parameter name

Thus, the following URLs are treated as illustrated:

http://www.example.com/path?a=2

has 1 dynamic parameter 'a', with value 2

http://www.xyz.com/p?c=5&a=2;;b

has 3 dynamic parameters 'a', 'c' with values 2 and 5 and 'b' with no value

http://www.example.com/&q=4;;b=4

has 2 dynamic parameters 'b', 'q' with values 4 and 4

Dynamic Parameter names or values entered in Site Explorer can contain alphanumerics (a-z, A-Z, 0-9) or '-' (dashes) or '_' (underscores)
