What is ASP.NET Full trust hosting? and A few good Full trust hosting plans.
In my previous post titled Install dasBlog, you need Full trust hosting I have talked about installing ASP.NET blog (dasBlog) and why it requires FULL TRUST hosting.
Today we will talk more about - What is full trust hosting and what is modified full trust hosting? A lot of web developers building web applications turn to web hosting companies to host their website. Web hosting companies offer a variety of plans.
Two type of plans largely offered are -
1. Shared web hosting or Shared plans
2. Dedicated web hosting or Dedicated plans
Shared plans, are the most economical and practical for low-traffic websites, can have anywhere from 25 to 150 separated websites hosted from the same web server. When hosting multiple websites on the same server, it is important that one website cannot affect or harm another site. For example, both the web hosting company and its customers want to prevent one website from, say, reading the connect string information from Web.config of another website.
Microsoft’s ASP.NET web technology / language allows for web hosting companies to define trust levels, which dictate what operations are permitted by ASP.NET applications. A web hosting company can either use one of the preset trust levels - Full, High, Medium, Low, or Minimal - or can create a custom trust level.
Full trust is the default, allows ASP.NET applications to execute native code, to read from the Registry and Windows Event Log, and to read and write to files outside of the application’s virtual directory. In short, with full trust one web application could delete the entire contents of another web application.

I am satisfied with both WebHost4Life.com and Alentus. The only reason I am using 2 different hostings is because I am linking between my existing sites and Google crawlers dont give a very good search ranking if your linked sites are on the same server.
Now most web hosting companies run in medium trust, which greatly reduces the potential for harm by limiting the set of operations an ASP.NET application can perform. But Medium trust will place a number of restrictions on an application, including limiting an application’s file access to within the virtual directory where the application lives. While the protection granted by medium trust is reassuring, its limited functionality can be a cause of worry for developers. There are a lot of web applications and components in the market which do require full trust to work as desired.
Now what will happen, in this scenario. In this case a lot of web hosts run the web applications as modified full trust, which is a modified version of full trust and web hosting companies block certain modules or permissions of full trust. e.g. you can change this full trust to be effective only for the needed functionality (or vice versa, disable it for the File IO). This can be done through the .NET Framework Configuration tools on the server (caspol.exe etc) but it will require some additional setup.
Also, there are ways of allowing applications run in full trust while still keeping them in a sandbox. Many respectable shared hosts do allow this as its required for applications like FlexWiki, but is something that must be requested.
Here is a list of ASP.NET web hosting companies providing modified FULL TRUST HOSTING service or modified Medium trust hosting service or running the server in a sand box.

Top 5 (five) Web Hosting Plans – Linux Web Hosting (PHP PERL MySql Apache Wordpress Blog Hosting)
For last few months I have been looking for the best hosting packages available online. Since I was planning to launch a BLOG (and had some other minor web projects in the line) I was researching for some of the best and economical (I had a pretty tight budget) hosting plans available in the market.
Last week, me and some of my blogger / webmaster friends were sitting at Starbucks in downtown toronto and a discussion popped up on the hosting packages we all have been using for the last 2-3 years. Well, it was a pretty useful discussion and we end up deciding the top 5 Linux hosting plans. Again it was all based on our past experience, this might not be the same for other webmasters or bloggers, but this list can definitely be used as a helping guide for both technical and non-technical users.
Some of my research was also done online and out of the following 5 web host packages I have personally used 3 of them and rest are being used by some of my blogger / webmaster friends.
I am creating a feature grid of all the hosting packages we discussed; I am also creating a custom Notes column at the end to enter notes based on our own experiences with that web hosting.
