2.1 frystyk 13: ** History
14: ** 8 Jun 92 Telnet hopping prohibited as telnet is not secure TBL
15: ** 26 Jun 92 When over DECnet, suppressed FTP, Gopher and News. JFG
16: ** 6 Oct 92 Moved HTClientHost and HTlogfile into here. TBL
17: ** 17 Dec 92 Tn3270 added, bug fix. DD
18: ** 4 Feb 93 Access registration, Search escapes bad chars TBL
19: ** PARAMETERS TO HTSEARCH AND HTLOADRELATIVE CHANGED
20: ** 28 May 93 WAIS gateway explicit if no WAIS library linked in.
21: ** Dec 93 Bug change around, more reentrant, etc
22: ** 09 May 94 logfile renamed to HTlogfile to avoid clash with WAIS
2.13 frystyk 23: ** 8 Jul 94 Insulate free from _free structure element.
2.1 frystyk 24: ** Sep 95 Rewritten, HFN
25: ** Nov 95 Spawned from HTAccess.c
