Hi,
Thanks for letting me know that suarve.
The issue is now sorted, so load times have decreased to acceptable levels (and not the 14s-20s load times I was initially seeing).
In a nutshell, if you want to run a php site, with TSOHost at least, it is best to use a Linux server.
If you want to host an asp/x page, its best to use a Windows server.
Hosting the php part of the site on a Windows server resulting in load times of between 14s-20s.
When you run a Hybrid server, with Linux bias, the server is essentially a linux server. Everything gets sent to it, as per normal. However, if any file/url extensions have .asp or .aspx on the end, these will get handled by a separate windows server.
Both the Linux and Windows server will have access to all the data on your web page.
Now, I'm pretty sure that it is more complex than what I have explained above, but I believe those are the main points.
Now, to configure a subdomain and assign it with an Windows server is such a no-brainer, IMO that should be the default method of hosting a website which uses both php and asp/x. Not running a hybrid server.
The above technique, cuts out ALL the headache that may occur if you are attempting to use the hybrid server, ie. your asp/x page not working, once it is uploaded to the webhost (although it worked fine on your development machine).
Based on my own experiences, I would advise against using a hybrid server - use it only if you absolutely have to.
Having been through the above though, I believe TSOHost offer fantastic value for money, where webhosts which offer both Linux and Windows hosting, at an affordable price, with good bandwidth allocation and good reliability, are very rare.
