Iis7 - Design And Implementation For Short URLs On IIS And .NET Stack?
Mar 7, 2011
I'm interested in creating "short URLs" a segment of pages on a site. However, this isn't in the traditional sense of "short URLs" like bit.ly where it will redirect to a different destination URL. I want the short URL to be the final destination.For example, one of these URLs might be http://foo/a/Afjbg, and when you navigate to it, it stays on http://foo/a/Afjbg (IOW, http://foo/a/Afjbg is visible to the user in the address bar).
If it was static content, I would just arrange the pages and folders into these names. But the content I will have on the site will be dynamically driven from a DB, so each page is generated on the fly. So the content looks logically different, but in reality is essentially the same .aspx page with dynamic content.How can this be accomplished on a Microsoft hosting stack? The platform is IIS 7 with ASP.NET 4.

I've been using the LongURL.org API for expanding short URLs. The great thing about this service is that it returns a long URL, the title of the actual page and meta-info.The real problem I have is that it seems to take an inordinate amount of time to fetch the data. I'm considering shifting the request to JavaScript so that the URL is fetched via an AJAX update panel, in order that the page loads quickly, and the URL data is updated while the user looks at the content (some search results).Does anyone know how else I could gather the info described above, n a better time-frame? I'm using C# ASP.NET but would consider solutions in other languages.

Is it better to have the calculated field returned with the rest of the results or is it better to calculate it later when you need it?
Example: I have a GridView that displays search results that has many fields like:
Application ID
Name
Account Type
Account Number
etc.
The account number field is not always consistently the same thing though. For accounts of type A they are eight digits long and for accounts of type B they are twelve.
After the search if they select a record and choose to continue the application I need to check the eigit digit account number for any access restrictions. All accounts of type A and B have an associated eigit digit account number, it is just that type B are the only ones to have the twelve digit number.
So should I add a redundant hidden field like "Common Account Number" to the search results and just hide it, thus making the heavily used search take slightly longer and making the results grid take up more space in the view state?
Or
Should I call the database when they try to continue the application and translate the Application ID into the eigit digit number so that I can use it to do my access restriction check? This will require one extra call to the database but the translation should be fast as both fields are in the same table and the application ID is a primary key. The continue application button will be used less as there are many other command options.

I am in the process of redesigning our main product, a knowledge database system for clients to access clinical and specialist advice articles. There is a requirement to add "Social Networking" to this allowing users to connect and post remarks etc...
This is somewhat similar to the Facebook wall scenario - where Articles, Photos, Groups, Products, Events, ActivityFeed can all have comments. I am at a lose as to the database design I would need to implement this. All comments must allow for Moderation/Approval/Spam Reporting etc...
I originally thought a individual table for each Comments entity ex: ArticleComment, ProductComment would work as the comments themselves are not all directly related. Each table having the same exact columns. But this makes life abit awkward as then this creates a separation between something that for all purposes is the same i.e. They are all comments.
The other design idea was to have a single Comment table with an "arc" type relationship to related tables with FK references back to the source.
The other option was to have a single Comment table with an Object Type and XID but this breaks the rules of relation and does not all for referential integrity.
I am at a lose and don't know what to do. I have asked over at SQLCentral.com and all I have done is raised more questions than answers about what to do.
Design 1: This would require exact copies of this table for all the entities.
-- Photo Comments --
CREATE TABLE dbo.PhotoComment
(
CommentID int IDENTITY(1,1) NOT NULL,
PhotoID int NOT NULL,
Body ntext NOT NULL,
ReportedAsSpam bit NOT NULL CONSTRAINT [DF_PhotoComment_ReportedAsSpam] DEFAULT (0),
IsSpam bit NOT NULL CONSTRAINT [DF_PhotoComment_IsSpam] DEFAULT (0),
IsApproved bit NOT NULL CONSTRAINT [DF_PhotoComment_IsApproved] DEFAULT (1),
CreatedDate datetime NOT NULL,
CreatedBy uniqueidentifier NOT NULL,
UpdatedDate datetime NOT NULL,
UpdatedBy uniqueidentifier NOT NULL,
IsDeleted bit NOT NULL CONSTRAINT [DF_PhotoComment_IsDeleted] DEFAULT (0),
CONSTRAINT [PK_PhotoComment] PRIMARY KEY (CommentID),
CONSTRAINT [FK_PhotoComment_PhotoID] FOREIGN KEY (PhotoID) REFERENCES dbo.Photo(PhotoID),
CONSTRAINT [FK_PhotoComment_CreatedBy] FOREIGN KEY (CreatedBy) REFERENCES dbo.aspnet_Users(UserId),
CONSTRAINT [FK_PhotoComment_UpdatedBy] FOREIGN KEY (UpdatedBy) REFERENCES dbo.aspnet_Users(UserId)
)
Design 2: The "Arc" relationship
CREATE TABLE dbo.Comment
(
CommentID int IDENTITY(1,1) NOT NULL,
CommentType char(1) NOT NULL CHECK(CommentType IN ('A','I','E','G','U','P')),
Body ntext NOT NULL,
ReportedAsSpam bit NOT NULL CONSTRAINT [DF_Comment_ReportedAsSpam] DEFAULT (0),
IsSpam bit NOT NULL CONSTRAINT [DF_Comment_IsSpam] DEFAULT (0),
IsApproved bit NOT NULL CONSTRAINT [DF_Comment_IsApproved] DEFAULT (1),
CreatedDate datetime NOT NULL,
CreatedBy uniqueidentifier NOT NULL,
UpdatedDate datetime NOT NULL,
UpdatedBy uniqueidentifier NOT NULL,
IsDeleted bit NOT NULL CONSTRAINT [DF_Comment_IsDeleted] DEFAULT (0),
CONSTRAINT [PK_Comment] PRIMARY KEY (CommentID),
CONSTRAINT [FK_Comment_CreatedBy] FOREIGN KEY (CreatedBy) REFERENCES dbo.aspnet_Users(UserId),
CONSTRAINT [FK_Comment_UpdatedBy] FOREIGN KEY (UpdatedBy) REFERENCES dbo.aspnet_Users(UserId),
CONSTRAINT [UC_Comment_CommentID_CommentType] UNIQUE (CommentID, CommentType)
)
-- Article Comments --
CREATE TABLE dbo.ArticleComment
(
ArticleID int NOT NULL,
CommentID int NOT NULL,
CommentType char(1) CONSTRAINT [DF_ArticleComment_CommentType] DEFAULT 'A', CHECK (CommentType = 'A'),
CONSTRAINT [PK_ArticleComment] PRIMARY KEY CLUSTERED (ArticleID, CommentID),
CONSTRAINT [FK_ArticleComment_ArticleID] FOREIGN KEY (ArticleID) REFERENCES dbo.Article(ArticleID),
CONSTRAINT [FK_ArticleComment_CommentID] FOREIGN KEY (CommentID) REFERENCES dbo.Comment(CommentID),
CONSTRAINT [FK_ArticleComment_CommentID_CommentType] FOREIGN KEY (CommentID, CommentType) REFERENCES dbo.Comment(CommentID, CommentType)
)
Design 3: The one that breaks the rules
CREATE TABLE dbo.Comment
(
CommentID int IDENTITY(1,1) NOT NULL,
ObjectType char(1) NOT NULL, /* A = Article, P = Photo etc... */
XID int NOT NULL, /* Would be the ID of the main entity being queried. */
Body ntext NOT NULL,
ReportedAsSpam bit NOT NULL CONSTRAINT [DF_Comment_ReportedAsSpam] DEFAULT (0),
IsSpam bit NOT NULL CONSTRAINT [DF_Comment_IsSpam] DEFAULT (0),
IsApproved bit NOT NULL CONSTRAINT [DF_Comment_IsApproved] DEFAULT (1),
CreatedDate datetime NOT NULL,
CreatedBy uniqueidentifier NOT NULL,
UpdatedDate datetime NOT NULL,
UpdatedBy uniqueidentifier NOT NULL,
IsDeleted bit NOT NULL CONSTRAINT [DF_Comment_IsDeleted] DEFAULT (0),
CONSTRAINT [PK_Comment] PRIMARY KEY (CommentID),
CONSTRAINT [FK_Comment_CreatedBy] FOREIGN KEY (CreatedBy) REFERENCES dbo.aspnet_Users(UserId),
CONSTRAINT [FK_Comment_UpdatedBy] FOREIGN KEY (UpdatedBy) REFERENCES dbo.aspnet_Users(UserId),
CONSTRAINT [UC_Comment_CommentID_ObjectType_XID] UNIQUE (CommentID, ObjectType, XID)
)
-- Ex: Get all comments for article ID 23.
SELECT * FROM Comment Where ObjectType ='A' and XID = '23'

I need to force every request to https://www.mysite.com (always with https and www)
The site is hosted in GoDaddy and I need to do it via IIS7 URL Rewrite Module.
I've been able to do the HTTPS redirect with the following code:
<system.webServer>
<rewrite>
<rules>
<rule name="Canonical Host Name" stopProcessing="true">
<match url="(.*)" />
<conditions>
<add input="{HTTP_HOST}" pattern="^mysite.com$" />
</conditions>
<action type="Redirect" url="https://www.mysite.com/{R:1}" redirectType="Permanent" />
</rule>
</rules>
</rewrite>
</system.webServer>
Test cases
http://mysite.com -> https://www.mysite.com OK
http://www.mysite.com -> https://www.mysite.com NOT WORKING
I guess the condition is not being satisfied when I enter www.mysite.com in the browser, so there's no redirect and the page serves as HTTP instead of HTTPS.
I think I just need to modify the condition pattern, but I have almost nothing regex knowledge and I need this asap.

i have a function that pulls URLs from various web resources. needless to say some are full valid URLS and some are relative as per the HTML of the page. below is my asp.net/ c# logic i derived for examining the URL and then generate a full usable URL from whats pulled from the site...
NOTE:
origianlurl is the full url of the first searched page, and relativeUrl is a url found within the searched page (it can be a full www.site.com or a /contactus.html)
private string ResolveRelativePaths(string relativeUrl, string originatingUrl)
{
if (relativeUrl.StartsWith("http") || relativeUrl.StartsWith("www"))
return relativeUrl;
if (relativeUrl.StartsWith("/"))
{
//get main url something.com
[code]...

I noticed the ActionNameAttribute lets you alias your controller methods. This is nice but I was curious if there was a comparable attribute for a controller name. Specifically, I have a controller with a lengthy name in c# world but would like to shorten / alias it in the actual URL. I was hoping for some kind of controllername attribute. Is there such a beast?

We are having an issue with a website...the short story is a date is selected from a calendar control such as 11/15/2010 but when it is saved it becomes 11/15/201 (last digit truncated). I am not the programmer debugging this so I don't know all the details, but it seems to be working on one server but has the problem on another.Could this have anything at all to do with the Regional and Language Options where you can specify your date format to be M/d/yyyy or MM/dd/yyyy? I would *hope* that would only change 02/09/2010 to 2/9/2010 and not truncate a year! But I remember this being a problem on the last project I worked on where dates were getting returned in a different format than that expected (again, suppressing the month from 2 digits to 1, or the day, but not the year...) Since this is machine-specific, it would explain why one server had it but the other didn't. But I don't want to suggest to the SA that he take a look, if I am way off.

Is there any way to tell a band to be shorter if there is no data in the fields in the bottom area of the band? Lets say we want to print in detail band:Line 1: Invoice Code, Invoice Total, Invoice Shipment ToLine 2: Invoice CommentsNormally if you set two lines of fields in detail band, Crystal Report force Min Height of Band to be the bottom of the second line, or bottom of objetcs in Band in general.I want to be able to tell him, make this Band As Short As possible, so if bottom controls or fields havent Data set the Height of Band to be not that tall !!!In other words if you let me "Can Grow" for some objects, please let me "Can shrink" for the whole Band.

Let's say we are building some public service that grabs the setup of a user (what server, user and pwd he wants to perform the call), logs in into that server and do some processing...
the process takes about 15 seconds to complete each user has a different setup (server/user/pwd), so the process needs to run against each one
if 1000 users tells the system to run the method at 1:00PM
How can I insure that the method is processed in the next 15 minutes?
What should be the correct approach to this little problem?
I'm thinking that I need to do something Asynchronously, and parallel processing could speed up things, maybe throttling the processes, maybe execute 100 calls per each 30 seconds?
I never did something like this and would love to get your feedback on ideas and future problems just to spend 100 hours of work and realize that I took a wrong road

I have a detailsView whose date values in a cell are currently being displayed in longDateFormat, i want to convert all date values in this DetailsView to short date.
For example, instead of 6/1/2010 12:00:00 AM, i want to display just 6/1/2010
For a Gridview, i can achieve that by the code blow
Protected Sub DetailsView4_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles DetailsView4.DataBound
If e.Row.RowType = DataControlRowType.DataRow Then
For i As Integer = 0 To e.Row.Cells.Count - 1
Dim cellDate As Date
If Date.TryParse(e.Row.Cells(i).Text, cellDate) Then
e.Row.Cells(i).Text = String.Format("{0:d}", cellDate)
End If
Next
End If
End Sub
How can achieve the same with a DetailsView?

My web site seems to be running quick. I have not deployed my web site yet, so I am the only one using it right now. The problem I have is if I am testing out the site and then I stop using it for a short period of time, when I come back the web site takes about 8-10 seconds to startup again. I did not rebuild the site I just simply stopped using it for a short period of time. It seems like after a short period of time I have to 'wake it up' again. Is this normal? How can I prevent this?

I've got a c# handler that serves up audio files I've generated using text-to-speech. When the files are written to disk they sound fine, but when I try and play them in a browser (via the handler) using a quicktime plugin it cuts them short at about 2 seconds.
Inside the handler I'm using the following code...
context.Response.ClearContent();
context.Response.ClearHeaders();
context.Response.ContentType = "audio/x-wav";
context.Response.WriteFile(fileName);
context.Response.Flush();

I'm using ASP.NET for a search app web site.My search retrieves exactly one result per fetch. Once the search is complete and the user selects "Update", a new result is fetched and the old result is written to the ViewState as a generic List. The new result replaces the old one.I am trying to get the page to update (via partial post-back), so that the old result drops down the screen and the new result sits on top of it. Much like the concept of a stack.
