Stop caching for a specific node (by nid) Drupal 7

Question

Ideally i want to set custom params for caching in some particular nodes using conditions in my template.php

E.g. algorithm: for node with known nid set custom caching params

But that's enough for my purpose simply exclude from caching particular node. I fond this solution: Stop caching for a specific node type Drupal 7 this is exacly what im looking for but how i can change condition of checking from node type to nid.

I know about CacheExclude module, but for me unwanted to install module for just exclude one node for caching.

I'll be very grateful for helping me.

Answer 1

A module with the below in it should stop caching on node 2. Change the number to do it on a different node id.

function MYMODULE_init(){
  if (arg(0) == 'node' && arg(1) == 2) {
    drupal_page_is_cacheable(FALSE);
  }
}
