Irule Table lookup

Question

when http request{&nbsp;set tls_cache_table "tls_cache_[virtual name]_[IP::client_addr]_[SSL::sessionid][table lookup $tls_cache_table] == 1 }{&nbsp; &nbsp; &nbsp; &nbsp; set tlsenforce_allow 1}i have not posted the complete URLi suppose the output for set would be tls_cache_example_vs_192.168.1.100_abcd1234.but in next line i could see we have a lookup for the above output with value = 1.&nbsp;what does it mean&nbsp;

It checks if there if $tls_cache_table is equal to 1.
Check the example iRule below.
when HTTP_REQUEST {
    set entry "entry_1"
    set entry2 "entry_2"
    
    # add entry2 to table
    table set $entry 1
    table set $entry2 "somevalue"

if { [table lookup $entry] == 1 }{
        log local0. "Entry $entry found and equals 1"
    }
    else {
        log local0. "Entry $entry not found or doesn't equal 1"
    }
    
    if { [table lookup $entry2] == 1 }{
        log local0. "Entry $entry2 found and equals 1"
    }
    else {
        log local0. "Entry $entry2 not found or doesn't equal 1"
    }
}
And the below output.
Feb 25 10:46:24 bigipa info tmm[11337]: Rule /Common/irule_table &lt;HTTP_REQUEST&gt;: Entry entry_1 found and equals 1
