The function 
.B service ~path ~get_params ()
creates a 
.B Eliom_service\&.Ocaml\&.service
associated to the path 
.B path
and taking 
.B get_params
as GET
parameters\&.
.sp
If the optional parameter 
.B ~https:true
is given, all links
towards that service will use https\&. By default, links will keep
the current protocol\&.
.sp
The optional parameter 
.B ~priority
allows one to change the priority
order between service that shares the same path\&. The default
priority is 0 ; if you want the service to be tried before
(resp\&. after) other services, put a higher (resp\&. lower) priority\&.
.sp
If the optional parameter 
.B ~keep_nl_params:`Persistent
(resp\&. 
.B ~keep_nl_params:`All
) is given, all links towards that
service will keep persistent (resp\&. all) non localized GET
parameters of the current service\&. The default is 
.B `None
\&. See the
eliom manual for more information about \&.
.sp
The optional parameter 
.B ?rt
is used to constrain the type parameter 
.B \&'rt
of the service in the case it is 
.B \&'rt Eliom_service\&.ocaml_service
\&.
Example:
.B service ~rt:(Eliom_service\&.rt : your_return_type Eliom_service\&.rt)

.sp
The function 
.B post_service ~fallback ~post_params ()
creates a
service that takes 
.B post_params
as POST parameters and share the
same path and GET parameters than the service 
.B fallback
\&.
.sp
POST parameters couldn\&'t contain a suffix parameter\&.
.sp
The service 
.B fallback
should be an (internal) attached service
without POST parameters ; it couldn\&'t be a preapplied service\&.
This argument enforces the creation of an equivalent service (
i\&.e\&. a service with the same path and GET parameters ) to be
served when POST parameters are missing\&. Thus, the user cannot put
a bookmark on a page that does not exist\&.

The parameter labelled 
.B ~prefix
contains all what you want to put
before the path\&. It usually starts with "http://" plus the name of
the server\&. The prefix is not URL encoded\&.
.sp
The whole URL is constructed from the prefix, the path and GET
parameters\&. Hence, an empty prefix can be used to make a link to
another site of the same server\&.
.sp
See 
.B Eliom_service\&.Ocaml\&.service
for a description of the optional
.B ~keep_nl_params
and 
.B ~rt
parameters\&.
