Just for future reference, really. I don't see much regarding perl out here, but that doesn't necessarily mean folks aren't using it.
Also, does anyone know good perl discussion boards similar to code-project?

I'm looking for the best way to restrict access to files, such as word docs, pdf, under an ASP.NET application. I use forms based authentication to allow access and I've set the IIS file mappings for my application so htm and asp pages use the ASP.NET dll. Everything works fine with these but doc and pdf files still get no security.
I was trying to implement an httpmodule to handle the onbeginrequest and check if the user has been authenticated but at that point in the process the user object has not been created yet. Anyone have an idea how to do this?

Best way is to do it per folder, not per file (so copy the PDFs and DOCs into the secured folder(s).)
In IIS go to the Directory Security tab of a virtual dir. properties. Then uncheck Anonymous access and check Basic Authentication. When you access that dir from an account not on the servers domain it will pop-up a dialog asking for a user name and password.
The problem with this though is you need a Windows account for users to use, though I think you can tap into it and link it through to a database rather than Active Directory.

I've used this in other projects but for this it won't work. These fles are in secured folders. The user had to pass through the forms authentication to view the aspx and html pages under it which contain links to the docs and pdfs. It is to much to ask (I have the scares) them to authenticate again to view a doc or pdf. As it is now navigating to the main page routes them through the authentication, just as it should. navigating the the doc directly does not. I want to check the authentication status, if not present redirect them tot he login page.

This problem perhaps is an impossible-to-answer qustion!
Well, I've uploded my ASP.NET code on Brinkster to ty it.... but it doesn't work!
I get this error message when I enter the page:
<br />
Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately. <br />
<br />
Parser Error Message: It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS.<br />
<br />
Source Error: <br />
<br />
<br />

Line 3: [authentication mode="Forms"]<br />
Line 4: [forms loginUrl="LoginPage.aspx"]<br />
Line 5: [credentials passwordFormat="Clear"]<br />
<br />
I've done a "Log in" test page with forms authentication, but it doesn't work for me on Brinkster. Can Brinkster's server be the leak?

Another irritating thing about ASP.NET. With ASP you just copied the file and it ran, with ASP.NET you have to maintain the integrity of the whole assembly and a whole lot of other setup tasks.
Basically this is what you need to do: You need to get Brinkster to make the IIS Virtual Directory in which your web.config file lies an Application. This can be done in IIS itself (right click virtual dir, click Create Application.)
If Brinkster won't do this for you (which they probably won't) then you need to locate your web.config file in an application folder, not just a normal folder. Bottom line is web.config must be in a virtual dir which is an IIS Application. Very bizarre but that is the deal unfortunatley.

Brinkster fixed this problem for me, about 15 minutes after I sent the mail. They're pretty damned approachable to be honest, don't underestimate them.

Well then I stand corrected, and pleased to be so. I really did not expect a free hosting service to be that responsive. GeoCities would just laugh at you and even some paid-for hosters would take days to do it and charge you for the work done (they charge by the hour of course, even though it takes only 5 minutes to do.)

This is my response from Brinkster:
<br />
Hello,<br />
Unfortunately, some of the General and General SE accounts have more difficulty than others. There are differences in the way the General solutions are configured than the Premium X4, but no difference between the General and General SE.<br />
<br />
The Premium x4 accounts do not experience this difficulty.<br />
<br />
We have been working with Microsoft for a solution this, but this has not been <br />
resolved at this time.<br />
<br />
All we can recommend at this time is that you follow the FAQ's at http://www.brinkster.com/GeneraldotNETFAQs.asp as well as the following steps;<br />
<br />
VS.NET UPLOADS<br />
You can upload to your account via Visual Studio.Net by doing the following:<br />
<br />
1- Load the Visual Studio start page (at Visual Studio start-up)<br />
2- In the menu to left, click "Web Hosting"<br />
3- Then, click the "Additional Providers" tab<br />
4- Then, click "Upload directly to your account"<br />
5- Finally, enter your Brinkster Account User Name and Account Password<br />
<br />
Note that if you are connecting to the Internet via a proxy server or firewall configuration, you may experience problems uploading via Visual Studio .Net. This is beyond our control and you or your ISP will need to configure your firewall or proxy server settings appropriately in order for you to use the feature.<br />
<br />
<br />
VS .NET UPLOAD FILE STRUCTURE ISSUES:<br />
The upload feature from within Visual Studio uploads projects the way that Microsoft creates them (each in to it's own folder). This is by default as Microsoft has set it up, and not able to be changed by us.<br />
<br />
To remedy this issue you have two choices:<br />
1. You can use the Visual Studio .NET upload facility, then create a default.htm (or .aspx) file that simply redirects visitors who type in just your domain name to the exact file you want them to go to (www.YourDomain.com/YourProject/default.htm).<br />
<br />
2. You can use FTP and put the files and folders in exactly the places you want them.<br />
<br />
<br />
Because the General and General SE accounts are free or low cost alternatives to Premium hosting, they are more restrictive. Such programs could not exist for developers if there were fewer restriction due to the costs involved.<br />
<br />
If you are unable to connect to a General or General SE account with Visual Studio .NET; In the short term the only alternative is to open or upgrade to a Premium account where these issues do not exist. In the long term it is an issue that we continue to work toward a solution, but at the moment remains unresolved.<br />
grrr!!!!
I have to find another FREE ASP.NET hosting somewhere I think!!

OUCH!
Really sorry about that Rickard. I've been using their Premium Accounts since way before .NET ever happened. It never occured to me that it might be different on a General Account. 
I like Brinkster Premium accounts because they're incredibly cheap for a service with very few restrictions, very high responsiveness and a pretty damned solid service (largely because they charge for lots of extras that I don't need).
I have three accounts at the moment  , but of course they're not for everybody. I'm glad you found a good free service.
Apologies again.
Paul

Well I think I'm sorry too...
But I've found my free .NET hosting account now and my forms auth... works for me!

this is NOT a limitation of asp.net, but a limitation of visual studio.
asp.net supports two models. the all-in-one-page model which asp uses, and the new code-behind model.
asp.net allows you to choose this on a per-file basis.
however, visual studio is designed ONLY for the code behind model, and there's no way around it.
Microsoft Asp.net Web Matrix, on the other hand, supports the all-in-one model, and still has a great page designer. It doesn't have intellisense on your code tho. It's available free on www.asp.net

I have to disagree. Just the other day I was teaching an ASP developer the basics of ASP.NET and created an ASPX page without a codebehind file. VS.NET did not complain and nor did ASP.NET running on IIS. You don't have to use codebehind, it is just recommended.

Ouch, I have to say that damns the Web Matrix in my eyes. Intellisense is a great invention.

I installed VS .Net and I, while the installation occured, remember reading that it was updating IIS and FrontPage. Now, I tried to test ASP.Net by creating a small project and when I try to run the .aspx file (localhost/somefile.aspx) it won't recognize the code and the page will be blank! A view source shows me that the code is actually there. ASP does work however.
Is there something that went wrong with the installation or I just need to set something up to enable ASP.Net???
Thanks!

Get back to me on the following:
- Open IIS
- Go to the default web site
- Right click on it
- Click properties
- Click the Home Directory tab
- Click the Configuration button
- Check in the list for .aspx
If it is there then I do not know why your system is not working. If it is not there, then you need to re-install ASP.NET onto your system (or alternatively you can re-map all the configurations but there is about 50 and they are a pain to do.)

Sure Paul, you just wanted me to enter all 50 entries manually!
What I don't understand is why this isn't automatically done during VS.Net's installation!?

It should do, and in most cases does. However we have experienced IIS "loosing" all ASP.NET mappings without much of a reason (it did this after 2 months of perfect ASP.NET running.)
I still have not figured out why it did it.

Yes, yes, it is true. I wanted you to experience my pain...

Hi,
how can I display an alert box from the code behind when an event failed ; like an insert in a Database ?
Thx.

Not to be too critical but you really need to go back to learning the difference between server side and client side.
You cannot ask for a messagebox in your server side code because it is being run on a server far away from the client. So your client will never see it.
You need to use JavaScript/ECMAScript (or even VBScript if you are so inclined) to create an alert box that the client can see.
You will need a function on your client side page which checks for a certain state (probably best to pass it by the querystring which JavaScript can access) and displays a normal JavaScript alert box if the state is true.
Though I would ultimately adivse not using an alert box to notify people of that kind of error. Rather use some text on the actual HTML page.

If I use an Access database on my page, can clients access that at the same time then?
I don't need an SQL Server or something similar?
