Registered session protocol names.
We do this to avoid lots of string compares. By normalizing the string names we can just compare their indices in this table.

| SessionProtocolNameRegistry::SessionProtocolNameRegistry | ( | ) |
Default constructor.
Creates empty registry with no names.

| SessionProtocolNameRegistry::~SessionProtocolNameRegistry | ( | ) |
Destructor.
Cleans up strings.

| int SessionProtocolNameRegistry::indexFor | ( | char const * | name | ) | const |
Convert a name to an index.
INVALID if it is not registered. Definition at line 646 of file RecHttp.cc.
