What's Parsero?

===============

Parsero is a free script written in Python which reads the Robots.txt

file of a web server and looks at the Disallow entries. The Disallow

entries tell the search engines what directories or files hosted on a

web server mustn't be indexed. For example, "Disallow: /portal/login"

means that the content on www.example.com/portal/login it's not allowed

to be indexed by crawlers like Google, Bing, Yahoo... This is the way

the administrator have to not share sensitive or private information

with the search engines.



But sometimes these paths typed in the Disallows entries are directly

accessible by the users without using a search engine, just visiting

the URL and the Path, and sometimes they are not available to be visited

by anybody. Because it is really common that the administrators write

a lot of Disallows and some of them are available and some of them are

not, you can use Parsero in order to check the HTTP status code of each

Disallow entry in order to check automatically if these directories are

available or not.



Also, the fact the administrator write a robots.txt, it doesn't mean

that the files or directories typed in the Dissallow entries will not

be indexed by Bing, Google, Yahoo, etc. For this reason, Parsero is

capable of searching in Bing to locate content indexed without the web

administrator authorization. Parsero will check the HTTP status code in

the same way for each Bing result.



When you execute Parsero, you can see the HTTP status codes. For example,

the codes bellow:



    200 OK          The request has succeeded.

    403 Forbidden   The server understood the request, but is refusing to fulfill it.

    404 Not Found   The server hasn't found anything matching the Request-URI.

    302 Found       The requested resource resides temporarily under a different URI.

    ...
