Logic For Fixing Relative Urls To Full Urls

Nov 16, 2010

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...

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

how can we change it? how can we set the web resource to be relative like this "../webresource.axd"

Best Way To Rewrite URLs?

Feb 16, 2011

I want to rewrite something like this:


to this:


Even to achieve the first link above, I need to replace capital letters and non-standard characters like é with e, and replace spaces with hyphens. Is all of this possible using URL Rewrite Module 2.0 or might I be better off coding some ASP? I'm new to .net and may have to do something in classic if I struggle. And I only just get by in ASP...

I've tried some of the tutorials on the official IIS website and have got through a simple rewrite wizard, but replacing characters seems more complicated, and I'm sure some of the tutorials have errors in them...

Rewrite Urls Not Working

Feb 17, 2011

I have a application which uses intelligencia urlrewriter to rewrite urls into seo friendly urls. Blog engine is integrated in this application under subfolder but shares webconfig with my application. Application runs perfectly on development server, but when i publish it to 2008/IIS7 server urls links don't work. Links similar to following work

<rewrite url="^/Abc" to="~/abc.aspx" processing="stop"/>
<rewrite url="^/Abc_123" to="~/abc-123.aspx" processing="stop"/>

But links like following fail to redirect and i get 404 errors

<rewrite url="^/Abc/(.*/)" to="~/abc.aspx?id=$1" processing="stop"/>
<rewrite url="^/XYZ" to="~/xyz.aspx?cat=school" processing="stop"/>

Anything which has query parameters in aspx url fails. I'm not sure what is causing this error on 2008/IIS 7 server and not on my VS 2008 development server.

How To Redirect 404 (bad Urls) To Homepage

Feb 22, 2011

I am using asp.net and when I type a bad url manually(in the browser) it gives me: The resource cannot be found. Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly. I want a bad url that doesn't exist to be re-directed to the home page. How do I do this?

.NET MVC Using IDs In URLs Default Routers?

Sep 2, 2010

I know the default routes in MVC include an id param which often maps to the identity of an entity as it's stored in the database. Now, often this is OK, but what about when you don't want someone to be able to manipulate it? Quite frankly, on many business apps this is very common. For example, you don't want someone to change the account number (not the best example, but you get the idea) in the URL for obvious reasons. So, you would need to validate the account number against the logged in user on every request. Obviously, that is not a realistic solution, and in webforms many people would store something like that in session. I am trying to rely on session very little in MVC, but aside from that would I just go old school and use hidden fields

Absolute URLs With Redirection?

Dec 2, 2010

My site was working fine before I starting working on incorporating URL redirection/rewriting. I have tried to preface all the URLs for graphic images and navigate URLs with a tilde and a slash ("~/"). However, now that I'm using rewriting on many of my pages, if the number of folders in the URL is 2 or less (such as MyDomain.com/Title/Author), it finds the graphics files without any problems, like before. When I view page source, I see that the HTML is calling for relative URLs that start with "../../", which is why it works for 2 or less folders in the URL. When there are 3 or more folders (such as MyDomain.com/Title/Author/Category), then it doesn't display the graphics files.

why I'm getting these relative URLs and so the files are not displaying correctly at times?

Long URLs From Short Ones Using C#?

Jul 4, 2010

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.

URLs are stored in a database, example:

I would like to arrange the above urls into a tree fashion as shown below (each item will be a url link). The final output would be a simple HTML List (plus any sub list(s))


home gallery info

page2 image2 contact
page3 map

Programming Language is C# , platform is asp.net


In the above example, we end up with Three Lists because in our example there is three main 'groups' eg: home, gallery, info.

Notifying Change Of URLs To Users?

Jan 7, 2011

I have recently updated a website. All of the urls have changed. Now I get traffic to old urls that doesn't exist anymore. However, most of these url's have corresponding pages on the new site. I believe most of the traffic to the old urls are spiders. What would be the correct way to handle this?

Preferably I'd like a solution that gives a nice experience for the real users if they type in an old url (or use an old bookmark they've made) but that also notifies the spiders of the change of url, so that they can update their registers. However, if the two are hard to combine, the last one is prioritized (since most of the traffic is spiders). I'm using ASP.NET

Auto-redirect URLs By Patterns In IIS 6?

Mar 9, 2011

I thought it should be a simple straight-forward matter but after struggling with it for too much time.

What I need is to redirect all requests for my web application that match the following pattern - "^(http://[^/]+/blogs/[^/.]+)/?$" to the path of "$1/Default.aspx".

(Using English rather than Regex: [URL]

The sub-directories in "blogs" do not physically exist, instead a 3rd party product deals with the requests to randomdir/Default.aspx", but when you go to "randomdir/" you get 404 not found, which is what I'm trying to fix.

I tried to use global.asax and also HttpHandler, but I couldn't get either of them to fire up on the requests to those 404 paths.

So, in short, what should I do to redirect paths of non-existing directories?
