Hi,

We are trying to evaluate BV Shopping Cart 5. We have installed the application to a hosted server, created the database. When we are trying to access the frontend or the backend site of bv software we get the following error (using IIS 6):

Any ideas of what is causing this error?

Many thanks,

Hi Marcus,

Many thanks, I will check with the web hosting company.

Alex

It would depend on the host. We support full trust when it is needed for an application.

No that is not the case.

If they run all the sites in the same app pool and store all the cache files at the site route then there is exposure to everything in the .NET cache, that would be a problem.

It sounds like .NET is either a hobby with the host and not their focus, or they are just trying to sell you on a full dedicated server box. We're all in favor of everyone having their own dedi, but most clients don't require it.

Hey Paul,

I wouldn't have all my clients hosting on Resposio's network if Noah didn't know what he was talking about :)

Don't jump ship on BV! Just get with the right host that is a certified solutions provider which requires thorough knowledge of the application.

HTH,
Matt

So I tried searching, and maybe I am searching for the wrong terms but I am looking for a list of ecommerce hosts that are known to work well with BV. Any input will be appreciated.



Thanks,

Try clicking on the Partners link at the top of this page.

Dave,

Your search should not be for BV hosting. What you really want to search for is ASP.Net hosting. Make a phone call to the hosting company before subscribing and let them know your requirements (in this case full trust). See if they are willing to do it. There are several Microsoft Gold Certified hosts who would not allow full trust for shared hosting. For instance DiscountASP.net didnt allow full trust till 2006. May be it has changed now.

But what you are looking for is this:
1. decent shared hosting package with full trust
2. appropriate amount of bandwidth as required by your website
3. be sure to checkout the server specifications. Many hosting companies have an average server (for instance a machine with 2 GB of RAM but they run about 100 websites off it). Similar is the case with processors.
4. ask for SQL Server 2005 standard edition. I noticed many hosts are now providing SQL Server 2005 Express edition. This version is free from Microsoft. And because its free, Microsoft has a few limitations on it. It can only utilize a single proc and 1 GB RAM.

Dont get me wrong but resposio and appliedi are great hosting providers. They are primarily the guys who host mostly BV stores. They are registered on BV site so obviously people go there. However, your options are definitely not limited. If you think your site is complicated and you have a lot of products and some custom programming work done, then you should do your home work. Stock BV5 works great out of the box. Once you start doing custom modifications to it the speed starts to take a toll. In that case you need a very high performing machine.

Over the years, I have had a great experience with Planet.com. I beleieve its their hardware. I have a few dedicated servers from them on which I host some of my BV stating sites for my customers. 99% of the time, folks come back to me ask me who is my hosting company. Only because they realize that the test site running in full debug mode is way more faster that their live site (some of which happen to be in a shared environment and some of them on a split dedicated server environment).

So you should do your homework to figure what you really want and asses your site. Then take a wise decision.

And now for guys who want to know more about why you dont want Full trust in a Shared environment? Read about it: http://blogs.msdn.com/ja...osting-environment.aspx. Default trust model in ASP.Net is Full trust. Hosting providers deliberately reduce the trust level to Medium trust to avoid this problem.

What Andy said above makes sense. It might make your host a little bit more comfortable by isolating three specific dlls. But believe me, if its a policy not to allow it, they will not, no matter whatever happens. I dont think they will create exceptions for you unless you intend to host a lot of sites with them.


But hey, whats wrong in giving it a try. :-)



Thanks,
