Insert host header using the edge client for iOS

Arrays give you the capability to store any kind of information based on an index, here are some examples about how to manipulate those data:

create array:

array set ::Connexiondata { }     Here the name of our array will be connection data

insert data:

set ::Connexiondata($myUserID) $uri    Here we insert our data ($uri) in our data through the index $myuserid

find data:

if {[info exists ::Connexiondata($myUserID)]} {   Here we check if we have some data for the index $myuserid
    set user_data $::Connexiondata($myUserID)  Here we retrieve the data based on the index
}

Check all data:

foreach { data } [array names ::Connexiondata] { on this loop we will extract all data inserted in Connexion data and assign it to $data
}

Remove data:

unset ::Connexiondata($index)  Here we remove the data that are linked to the index $index

One piece of warning, You don't have any kind of timeout with array so you need to be careful how much data you handle since you are limited to 4Mb.

Usually it is possible to do the same thing with the session command which contains some timeout information.
