If your website is hosting a forum or a blog that allows comments to articles you've posted and you allow registrations and postings without some mechanism for verifying the registrations are coming from a human rather than an automated script, you will likely get an enormous amount of spam posted on your site, since there are many systems out there on the ...

You just got introduced to bots :) Looks like you are running a vanilla version of software like phpBB or WordPress etc. What are bots? (Source: Wikipedia) Bots are an army of (mostly compromised) machines doing whatever their bot head asks them to do. In most cases, they just post spam messages with links. Read more about the command and control ...

If one tries to have one machine do the work of two, some parts of the machine will need to be larger but run at the same speed, some can stay the same size but will need to run faster, and some will need to be larger and faster. The extent to which it makes sense to combine the roles of smaller machines into a larger one, or split the roles of larger ...

Let's take the problem at small scale. A tiny office with one server running mail, ActiveDirectory, file share, and the web site for the company. Hackers hit it and you have to reboot because IIS is messed up. Or Exchange needs an update and a reboot. Or Active Directory got corrupted. Any of these isolated "one service is down" problems affects the ...

Size limit. We like to pretend that a single box with multiple processors, memory chips and disks is uniform. This isn't entirely true, but it's true enough if your numbers don't get too big. There are technical limits on heat, energy, proximity etc. which means there'll always be a practical limit on how big a single server can be. Scalability - there's a ...

From Rear Admiral Grace Hopper: On the building of bigger computers: "In pioneer days they used oxen for heavy pulling, and when one ox couldn't budge a log, they didn't try to grow a larger ox. We shouldn't be trying for bigger computers, but for more systems of computers." source

Stephen explains the major consideration to make when deciding on a systems architecture: the tradeoff in vertical and horizontal scaling. I'll add a few other considerations: Separation of concerns: you mention multiple radically different systems: reverse proxies, DB, content servers, etc. From a maintenance and security standpoint it is clearly ...

A single powerful server can only be upgraded so far. Once you have the most powerful server available, your site cannot grow more without splitting it between servers or making it more efficient. There is also the cost factor. A single server that is super powerful may cost ten times as much as two servers that are half as powerful. You want to be able ...

Don't duplicate the site. As recommended by Google, you should use a 301 redirect. https://support.google.com/webmasters/answer/93633?hl=en Page content added for completeness for future visitors: https://www.youtube.com/watch?v=r1lVPrYoBkA If you need to change the URL of a page as it is shown in search engine results, we recommend that you use a ...

If you want thingeroo.com to point to somedude.github.io/thingeroo then this would require github, in this case, to cooperate by acting as a proxy. Fortunately github actually does this! All you have to do is: Specify an A Record for thingeroo.com that points to the appropriate github server (192.30.252.154 or 192.30.252.153) Add a CNAME file in your ...

CNAME records don't have anything to do with redirecting HTTP requests. They're for host names. You can't use a CNAME record for this purpose. Fortunately, almost all domain registrars provide a service that will allow you to redirect requests to your domain to somewhere else. They do this by setting your DNS A records to their web servers where a ...

dan says: When you log into GoDaddy, under My Account -> Products you should see "SSL". Click the "Options" button there and select the checkbox to cancel it. It will take a day to remove the SSL from your hosting account. You may also need to call the hosting department, or send them an email if it's still there (clear your browser cache when checking). ...

Look into using a reverse proxy. It will work whether or not the sites are served from the same server or not. One way to do so would be to use mod_proxy with the Apache webserver. The configuration of the virtual host for public would look like this: <VirtualHost *:*> ServerName public.com ProxyPass / http://private.com/ ...

If you are on the same server, set the document root for public.com to the same document root as private.com. i.e. Point them both to (for example) /home/websites/public_html and they will both show exactly the same content.

This question is opinion-based but I'd still like to help you out here. Advantages: Well, it's free! GitHub's CMS gzip & minify A fast CDN Disadvantages: No 'good' cache No 'good' SSL support No good cookies system Of course, Github pages is free so I imagine there has to be downsides. I understand you're thinking that but GitHub pages is ...

Either: Your attempt at adding captcha can be bypassed. The email address is known and the spam is not coming through the contact form. Its very hard to tell exactly what is wrong without a link to the site to investigate. I am the author of free open source contact form software that is designed to solve this very problem. My contact form: Never ...

Ok zerohedge it sounds indeed like you're a little confused. To help clarify, what you are trying to do is setup an independently hosted website running Wordpress and to use a subdomain for this. Ideally you would follow these steps: Setup website hosting for myproject.mycorporation.com (avoid using a different domain such as mydomain.io), you will not ...
