Description of problem:
I'm missing flexibility in jwhois.conf server options to handle some webwhois 
servers. See the following examples:

I have to handle the following second level domain,

--- snipp ---
"\\.om$" = "www.omnic.om";

"www\\.omnic\\.om" {
  http = "true";
  http-method = "POST";
  http-action = "/onlineUser/whoisMain.jsp";
  query-format = "domainName=${+2}&domainCategory=.om&sourcePage=WHOISLookup";
}
--- snapp ---

but that conflicts with the following top-level-domain, because of the same
server options name which has different parameters in query-format:

--- snipp ---
"\\.co\\.om$" = "www.omnic.om";
"\\.com\\.om$" = "www.omnic.om";
"\\.edu\\.om$" = "www.omnic.om";
"\\.gov\\.om$" = "www.omnic.om";
"\\.med\\.om$" = "www.omnic.om";
"\\.mil\\.om$" = "www.omnic.om";
"\\.net\\.om$" = "www.omnic.om";
"\\.org\\.om$" = "www.omnic.om";

"www\\.omnic\\.om" {
  http = "true";
  http-method = "POST";
  http-action = "/onlineUser/whoisMain.jsp";
  query-format = "domainName=${+3}&domainCategory=.${2}&sourcePage=WHOISLookup";
}
--- snapp ---

I think, we need some kind of regular expressions when using the placeholders 
${} inside of query-format. The issue always comes up, when a domain allows 
registrations under second and third level and has separate input fields in
the webwhois.

Another example:

--- snipp ---
"\\.kg$" = "kynseweb.messagesecure.com";

"kynseweb\\.messagesecure\\.com" {
  http = "true";
  http-method = "POST";
  http-action = "/whois.asp";
  query-format = "domain_name_pref=${+2}&domain_name_suff=.ky";
}
--- snapp ---

But I need the following section in order to handle the third levels correct 
(.org.ky):

--- snipp ---
"\\.com\\.kg$" = "kynseweb.messagesecure.com";
"\\.edu\\.kg$" = "kynseweb.messagesecure.com";
"\\.gov\\.kg$" = "kynseweb.messagesecure.com";
"\\.net\\.kg$" = "kynseweb.messagesecure.com";
"\\.org\\.kg$" = "kynseweb.messagesecure.com";

"kynseweb\\.messagesecure\\.com" {
  http = "true";
  http-method = "POST";
  http-action = "/whois.asp";
  query-format = "domain_name_pref=${+3}&domain_name_suff=.${2-}";
}
--- snapp ---

Maybe they already can unified somehow, but how? I found nothing when having
a looking to the documentation. Ideas? Or do we have to implement something?

An ugly workaround could be some kind of a lynx-wrapper in before, which knows
the worse top-level-domains and handles exactly that using regular expressions.
But I would like to see this sane solved and in jwhois directly. Maybe we can
hack in such a functionality into jwhois?

Version-Release number of selected component (if applicable):
jwhois-4.0-12

How reproducible:
Everytime, see above and below.  

Actual results:
Missing flexibility in server options to handle some webwhois servers

Expected results:
Maybe some regular expression handling or something else to handle second
and third level domains correct.
