I have an asp.net web application that is being hosted on an internal network. In my testing environment of course it gets hosted out on localhost:01010/Views/page.aspx. now whenever I take it live the Url changes to server_name/folder 1/folder 2/views/page.aspx. what I am trying to do is get a new page to open up as server_name/folder 1/folder 2/Uploaded_Images/randomimage.png. Now I Can get the url, but as soon as I do a single ".Remove(url.lastindexof("/")+1)" it returns "server_name/folder 1/folder 2/Views". The I perform my second ".Remove(url.lastindexof("/")+1)"
and the it only returns "server_name/". I am ripping my hair out at this one and am hoping somewhere in the world a .net developer already has this built in. Appreciate all the help.
Also just to specify this is webforms and not mvc. also there is no ajax or page manipulation going on except for a response.write to open the new page.
You don't need the +1, this works:
var url = "server_name/folder 1/folder 2/views/page.aspx";
url = url.Remove(url.LastIndexOf("/"));
url = url.Remove(url.LastIndexOf("/"));
Or you could do it like this:
var parts = url.Split('/');
var newPath = string.Join("/", parts.Take(3));
I assume you are talking about URL's used as links to parts of your site and not physical paths on the file system.
In most cases, you should be able to use methods that construct paths on the fly. For example, in any of your .aspx files (or .aspx.cs files), you can use the ResolveUrl method, like this:
Some link
If there are any places where you need the full URL including the domain (like for email notifications or something like that) then what I have done is keep a static variable accessible to my whole application that gets set the first time Application_BeginRequest runs:
void Application_BeginRequest(object sender, EventArgs e) {
if (SiteRoot == null) {
SiteRoot = HttpContext.Current.Request.Url.GetLeftPart(UriPartial.Authority) +
(VirtualPathUtility.ToAbsolute("~") == "/" ? "" : VirtualPathUtility.ToAbsolute("~"));
}
}
That will pull the full URL from the Request details (the URL that the user used to access your site), without any trailing slash.

I am given a code and on one of its pages which shows a "search result" after showing different items, it allows user to click on one of records and it is expected to bring up a page so that specific selected record can be modified.
However, when it is trying to bring up the page I get (by IE) "This page cannot be displayed".
It is obvious the URL is wrong because first I see something http://www.Something.org/Search.aspx then it turns into http://localhost:61123/ProductPage.aspx
I did search in the code and found the following line which I think it is the cause. Now, question I have to ask:
What should I do to avoid using a static URL and make it dynamic so it always would be pointing to the right domain?
string url = string.Format("http://localhost:61123/ProductPage.aspx?BC={0}&From={1}", barCode, "Search");
Response.Redirect(url);
Thanks.
Use HttpContext.Current.Request.Url in your controller to see the URL. Url contains many things including Host which is what you're looking for.
By the way, if you're using the latest .Net 4.6+ you can create the string like so:
string url = $"{HttpContext.Current.Request.Url.Host}/ProductPage.aspx?BC={barCode}&From={"Search"}";
Or you can use string.Format
string host = HttpContext.Current.Request.Url.Host;
string url = string.Format("{0}/ProductPage.aspx?BC={1}&From={2}"), host, barCode, "Search";
You can store the Host segment in your AppSettings section of your Web.Config file (per config / environment like so)
Debug / Development Web.Config
Production / Release Web.Config (with config override to replace the localhost value with something.org host)
and then use it in your code like so.
// Creates a URI using the HostUrlSegment set in the current web.config
Uri hostUri = new Uri(ConfigurationManager.AppSettings.Get("HostUrlSegment"));
// does something like Path.Combine(..) to construct a proper Url with the hostName
// and the other url segments. The $ is a new C# construct to do string interpolation
// (makes for readable code)
Uri fullUri = new Uri(hostUri, $"ProductPage.aspx?BC={barCode}&From=Search");
// fullUrl.AbosoluteUri will contain the proper Url
Response.Redirect(fullUri.AbsoluteUri);
The Uri class has a lot of useful properties and methods to give you Relative Url, AbsoluteUrl, your Url Fragments, Host name etc etc.
This should do it.
string url = string.Format("ProductPage.aspx?BC={0}&From={1}", barCode, "Search");
Response.Redirect(url);
If you are using .Net 4.6+ you can also use this string interpolation version
string url = $"ProductPage.aspx?BC={barcode}&From=Search";
Response.Redirect(url);
You should just be able to omit the hostname to stay on the current domain.
I am working in an application where I am using localization. For localization both admin and user can change the language. If admin changed recently, that change will be affected to all users.
For Ex, Admin changed the language to en-US, so the url will be http://localhost:81/en-US/form
Then, If user trying to change the language, http://localhost:81/fr-fr/form like this, we need to redirect to http://localhost:81/en-US/form. I need to change that part alone in pathname.
I have tried like,
if (!data.Status)
{
// data.Data contains ("en-US") this part of url
var URL = window.location;
URL.replace("/" + data.Data, "/" + window.location.pathname.split('/')[1]);
}
So, Url changing like http://localhost:81/en-US not http://localhost:81/en-US/form.
If I try this in c# url will be like, url wil be like http://localhost:81/controller/view?languagetag=en-US/something
How can I change this part alone ??
Any idea to achieve this in script or suggest me to do in C#.
Sorry for bad title, I really don't know how to describe this problem. Any suggestion is welcome.
I have to implement this in one large asp.net project (c#):
- user enters some url in browser, which should be in this form:
http://servername/directory/M1234N/2
where M1234N and 2 are some example values that can be different based on user needs.
Based on those two values, page should be redirected to another page. Basically, program should extract those two values from URL and based on that calculate where to redirect.
Is this even possible?
Thank you!
PS Sorry for bad post and title, feel free to correct me anytime
Yup it is possible. Initially, you have to read these values from the query. In order to do so, you should read the url
string url = HttpContext.Current.Request.Url.AbsoluteUri;
Then you have to split it based on "/".
string[] splittedUrl = text.Split('/').ToArray();
This way you will get an array, whose last two elements would be that you want:
string val1 = splittedUrl[splittedUrl.Length-1];
string val2 = splittedUrl[splittedUrl.Length-2];
Now based on the val1 and val2 you can find the page you want to redirect the user and you can redirect it as you would do in any other case.
Use this method.
Add a global.asax file to project
add this method to global.asax ile
void Application_BeginRequest(object sender, EventArgs e)
{
string para2;
string para1;
string CurrentPath = Request.Path.ToLower();
if (CurrentPath.Contains("http://servername/directory"))
{
//Get the two parameters from the url, here i am assuming that directory is static
//If not then you can change below two line for getting the passed parameters from url.
//I think it is easy task just use some string functions
para2 = CurrentPath.Substring(CurrentPath.LastIndexOf("/"));
para1 = CurrentPath.Substring(CurrentPath.IndexOf("directory"), CurrentPath.LastIndexOf("/"));
//Now work on these parameters and calculate the redirect page.
//Replcing the httpcontext with new page
HttpContext MyContext = HttpContext.Current;
MyContext.RewritePath("path of your new page according calculations");
}
}
In this method the application beginRequest will be called for every request.And you work on the current url.
I need to get the url of the site so that I render a user control on only the main page. I need to check for http://foo.com, http://www.foo.com, and foo.com. I am a bit stumped as to how check for all 3. I tried the following which does not work.
string domainName = Request.Url.Host.ToString();
if (domainName == "http://nomorecocktails.com" | Request.Url.Host.Contains("default.aspx"))
{ //code to push user control to page
Also tried
var url = HttpContext.Current.Request.Url.GetLeftPart(UriPartial.Authority) + "/";
Any thoughts?
You need to check if the Request.Path property is equal to / or /Default.aspx or whatever your "main page" is. The domain name is completely irrelevant. What if I accessed your site via http://192.56.17.205/, and similarly, what if your server switched IP addresses? Your domain check would fail.
If you utilize the QueryString to display different content, you'll also need to check Request.QueryString.
Documentation for Request.Path:
http://msdn.microsoft.com/en-us/library/system.web.httprequest.path.aspx
Documentation for Request.QueryString:
http://msdn.microsoft.com/en-us/library/system.web.httprequest.querystring.aspx
If you need the user control to only appear on the main page (I'm assuming you mean home page), then add the code to call the user control to the code behind of that file.
If this code is stored in the master page, then you can reference it like:
Master.FindControl("UserControlID");
If you are only using the one web form (ie. just Default.aspx), then you can check that no relevant query strings are included in the URL, and display only if this is the case:
if (Request.QueryString["q"] == null){
//user control code
}
However if you are using this technique then I would recommend using multiple web forms using master pages in the future to structure your application better.
The ASP.NET website has some good tutorials on how to do this:
http://www.asp.net/web-forms/tutorials/master-pages
I have a URL like:
www.zzz.com/ExternalDocuments/ExternalDocumentUpload.aspx?hjgbasdjfjsggfsdf
I want to provide something short for ExternalDocuments/ExternalDocumentUpload.aspx. I don't want to shorten the whole url.
It sounds like what you want isn't "shortening" -- where a service like e.g. bit.ly is used to shorten the entire URL for use in Twitter or suchlike -- but "URL rewriting".
This takes a "friendly" path provided by the user -- to the right of the "/" -- and turns it into the URL you need for ASP.NET to find the page.
There's a few different ways to do this depending on precisely which flavour of ASP.NET and IIS you're using. ScottGu has a good roundup here:
http://weblogs.asp.net/scottgu/archive/2007/02/26/tip-trick-url-rewriting-with-asp-net.aspx
and for IIS7 I've used the one here:
http://www.iis.net/download/URLRewrite
You can set up url rewriting in global.asax file, on Application_BeginRequest event, that would run on every request, checking requested url and, if needed, redirecting it to desired url. You can make the checking like this:
protected void Application_BeginRequest(Object sender, EventArgs e)
{
if (Request.RawUrl== "/someShorturl/page.aspx")
{
HttpContext.Current.RewritePath("/ExternalDocuments/ExternalDocumentUpload.aspx?hjgbasdjfjsggfsdf");
}
}
So, if user goes to "www.zzz.com/someShorturl/page.aspx", he will get "www.zzz.com/ExternalDocuments/ExternalDocumentUpload.aspx?hjgbasdjfjsggfsdf" page, although url in the browser won't change.
If you'd like to change shortened url into long original url, you can call Response.Redirect instead the RewritePath method.
This example is for one speciffic url, but you can create more complex logic, of course.
