Ngrok – Free Web Tunneling

In the verge of today’s web development we encounter cases that in order to proceed we need to have a public accessible URL. Thankfully, Ngrok provide a free service to do this.

What it does is tunnel your machine to a Ngrok URL with a specific port. We just need to download the ngrok.exe from their website and run the command like

ngrok http 80

With this command your service on your local machine that is running on port 80 will be mapped and accessible publicly for FREE. For a full documentation view it here.

God Bless!

Thanks,

Today 3/17/2014 again my tjsa.tk has been removed without any notices and worst of it all other domains I have has been remove. Unfortunately I will not recommend dot.tk anymore. Its a waste of time to follow up and even use it. Buy a domain instead.

Single Login Per User

Have ever wondering on how can you handle a Single Login Per User on your website? Yes may be you will need to disable multiple login due to some security reasons. So here is the only perfect way that you can do it:

When the user login flag on the database either an IP(for single login on a network) or Session Id of the user (for single login across all network).
Then every time the user visit a page in your website check if the flag has been change.
If the flag has been change then log off the current user

That way you can manage only one login per account depending on what situation you want it to happen. If you are thinking that you don’t want to logoff the current user but disable other login that will be impossible to happen. Because you can’t stop a user from closing the browser or shutting down the computer. In such cases you can’t handle on your script.

The index.html, What is it?

4 Replies

Have you ever wonder what is an index.html?

An index.html, in some cases default.html, is the main page of our website. It is the default file that our browser/server look for to view our website. The file extension(.html) also varies to what programming language we are using.

PHP -> index.php
ASP -> index.asp
ASP.Net ->index.aspx
JSP -> index.jsp
HTML ->index.html

It can also be set on some programming language on what specific file should the browser/server look for.

So be reminded that if you are developing a website that you should set the main page’s file name of your website to index.
