I am using Latest Ubuntu Linux and Apache2 Web server. I have made my Home directory as a Root directory of the Web server. Here I put multiple websites in different folders like

```
home/site1/
home/site2/

```

And they load on Browser like this

```
http://123.456.789.102/site1
http://123.456.789.102/site2

```

So now what I want to do is, I have one more directory as 

```
home/mainsite/

```

And I want it to load when I directly use this URL in browser

```
http://123.456.789.102

```

Other thing about this site is, it is built using Symfony framework. So after configuration, the site will load using this URL

```
http://123.456.789.102/web

```

So next I have to do some configuration to remove /web from URL

I am not good at configuring Apache server files. So if anyone can guide me out, that would be very helpful.

Thanks in Advance
