What is 404 Error Page & how to create?

All we have seen. You’re navigating a website and you click a link, but the page does not load other than a few words of “404” and some additional information.

So, what is a 404 page? It basically tells you that the server cannot find the website page you’re looking for. However, instead of using the 404 error page by default, you can create one. Here’s how it’s done.

First, you need your .htaccess file that should be in the directory of your Web server where you have hosted your pages. If you cannot find, you have to create one. You’ll probably have to contact your hosting support to ask them how to create it or edit it. You might want to use a text editor and then upload it to the server, or create and edit directly from the server tool they use.

Once you have the .htaccess file created and edited by adding a line like the following:

ErrorDocument 404 https://www.esds.co.in/404page.php

Now that the line in the .htaccess file points to the error page we create. This is just an HTML document. Once you’ve created, save it and call 404page.php or html as per url structure. The next step is to upload the .htaccess file to the server and the error page.

Once you are located in the corresponding directory we have to get it going. We do this by changing the attributes CHMOD to 644. You can do through a Telnet or FTP program of your choice. If you connect via Telnet and do it via command, you must type the following:

chmod 644 .htaccess

Now you must try if it works. Simply type your domain in the browser points to a page that does not exist, and you should see the 404 error page. If not, make sure the CHMOD is configured correctly, and if you still have problems, your Web hosting company can surely help you.

BCC in an Email

BCC is a function used in emails and have an interesting purpose in some cases. An average email recipient has three classes, the first is the usual “To” recipient “CC” and finally the “BCC”. The first one is intended for the main recipients of the email, the second is for those recipients who are to receive a copy of the mail, and finally, the BCC who will receive a copy of the email but their email will not be seen by the other recipients. The usefulness of the BCC is to allow a long list of people interested in receiving the email, but for some reason they want to remain hidden.

The “To” field is for sending mail to people who are active in a project or subject of the email. This field addresses all visible together by interest of the email. This is because it is assumed that all are related to work and therefore have to keep in touch. On the other hand, the “CC” field are people who will not directly addressed email, and can also be interesting to know their e-mail each other.

The “BCC” field may be people who are related in some way to the job or project, but it is not essential that your email addresses are known. This can be for several reasons. The most common use for the primary recipient does not know who is receiving a copy of the email. While this can be done easily by a second copy of the message body and by forwarding the BCC field allows us to do this in a simple way and in a single step.

The BCC recipient will see the main direction on who is sending the mail (the “To” field), but the main target will see it is the only one who is sending the email. In mailing lists, the BCC camp is normally used as a courtesy for individuals who are part of the list. Even if everyone agrees to share your e-mail, have a mailing list too long is a risk of spam. It is also a risk for the subject of certain viruses, which include all the email addresses to replicate. The BCC field stops get all directions.

The meaning of BCC is Blind Carbon Copy, and is a term that predates the computers we know. At other times, when letters were written, it was done alternating pages of carbon paper between normal paper where it was written. When writing a letter several copies were made. Addresses and greetings were often left blank during the carbon copy, and then added by hand later. In this way the recipient does not know who else was receiving the letter.
