what is the code through which I can ask any search engine not to crawl my own site or part of the site?

[shabbir]

Multiple ways.

1. In robots.txt add the following line
User-agent: *
Disallow: /

2. In Head Meta you can specify no crawl or index like

<meta name="robots" content="noindex,nofollow" />

3. Last but by no means least is make it a password protect directories using Apache

Disallow: / this is the code. this prevents search engines from crawling your site
