URL Rewriting Based On QueryString Parameters

Apr 11, 2010 06:55 AM

I wanted to ask about URL rewriting. I want to map this: [URL]
To: [URL] Being DVD players product id 123.

Also I will like to map sub domains like this:
From: [URL]
To: [URL]

Being John Doe user id 123. I will like to do this by getting the respective ID (for products and users) from a database based on product id name (dvdplayers) and sub domain name (johndoe). Where can I intercept these 2 (sub domain string and product name string) and based on this getting the info from DB and "rewrite" the URL's?

How To Route Legacy QueryString Parameters In MVC 3

Mar 11 at 22:08

I am using a third party service that does an async callback to a URL I provide to them. So I tell them to use [URL] This must obviously map to an Incoming() method on my StatusController.

However, what I don't have control over is the format of the parameters they call my URL with. E.g. They will do a callback such as: [URL] I want to map this to the parameters of my action method: Incoming(string param1, string param2, int param3)

How do I do this?

Send Multiple Parameters Via Querystring Asp

Mar 5 10 at 14:23

Which is the best way (in performance and security) to send multiple parameters to a web page (on a different server), considering that the length of the parameters may vary because I'm sending a list of products, and the customer may have selected more than one product, so we need to send each product on the querystring to the other page. For example (I'm on C#); I want to call a web page like this:

Simple Querystring: thepage.asp?Product=1&Name=Coffee&Value=1.99
Json: thepage.asp?{"Product":"1","Name":"Coffee","Value":"1.99"}
XML: thepage.aps?<xml><Products><product>1</product><name>Coffee</name><Value>1.99</Value></Products>

(Obviouly considering we can't send special characters via querystring, but I put them here for better understanding) Which will be the better way (performance, security)?

Iis7 Url Rewrite - Optional Querystring Parameters?

Mar 9 10 at 23:04

I'm using the iis7 URL Rewrite module and it's working fine, except for two things. Being new to this, I might be missing something obvious.

1) My URL gets converted from to This works fine, but if I add a trailing / , a few images on the site disappear, wheras a few don't. (They're all in the same location). However, the search results are fine.

2) Is it possible to make cerain querystrings optional? Server side, this is implemented (i.e. if nothing is entered, then assume a default value). But how would this work with the URL rewrite module? e.g. would search for John and use a default value for the sName parameter.

Web Forms :: Can't Get SitemapPath Control To Read Querystring Parameters From Web.sitemap Properly

Nov 20, 2007 11:53 PM

I have a sitemappath control:

Text='<%# Eval("title") %>'
NavigateUrl='<%# Eval("url") %>'
Text='<%# Eval("title") %>'
This works great for urls which match values in Web.sitemap, such as:
title="Trial Research"
description="Trial Research"

The problem Im having is that when dynamic params are passed in the querystring, the sitemappath doesnt find the page as a result. So if the url of the page gets appended dynamically to: url="~/Lib/Rs/List.aspx?id=trial&id=123" the title and url values dont get displayed. My question is, can I add a special character to Web.sitemap nodes so it doesnt evaluate the querystring and will just look for the page, List.aspx?

Modify Request Querystring Parameters To Build A New Link Without Resorting To String Manipulation

Apr 6 10 at 14:54

I want to dynamically populate a link with the URI of the current request, but set one specific query string parameter. All other querystring paramaters (if there are any) should be left untouched. Eg, imagine I want to build a link back to the current page, but with the querystring parameter "valueOfInterest" always set to be "wibble" (I'm doing this from the code-behind of an aspx page, .Net 3.5 in C# FWIW).Eg, a request for either of these two:


would become:


And most importantly (perhaps) a request for:


would preserve the boring params to become:


Caveats: I'd like to avoid string manipulation if there's something more elegant in that is more robust. However if there isn't something more elegant, so be it. I've done (a little) homework: I found a blog post which suggested copying the request into a local HttpRequest object, but that still has a read-only collection for the querystring params. I've also had a look at using a URI object, but that doesn't seem to have a querystring

Change QueryString On Postback?

Feb 20, 2008 02:39 PM

I am trying to change the QueryString parameters with a btnClick event that is causing a postBack. I've done it with Response.Redirect so far but as far as I understood Response.Redirect doesn't load the loadViewState (or sth) method and I cannot use ViewState with the R.Redirect. So does someone know how to do it? I mean its an asp:Button with an OnClick event - and I want it to change the parameters in the url while performing its postback.

upnlB: here I have a checkbox list X which filters the search results (allows for narrowing the results)

Now when a checkbox in list X is clicked, I do an autopostback, then I need to update the querystring (current URL in users browser) and also update the search results.

I have no idea how I would go about this! Im seeing difficulties in changing the URL without doing a response.redirect/server.transfer and reading from the querystring to update the search results.

Event Handler And Redirecting From URL With QueryString

Mar 19 10 at 16:32

I have a page request with a QueryString, say [URL]. The page is displayed in a browser. Now there is an asp:LinkButton on the page which should enable the user to open the page without the QueryString (as if he had entered [URL] directly in the browser's address bar). I had two ideas:

1) Use the PostBackUrl attribute of the LinkButton:
<asp:LinkButton ID="LinkButton1" runat="server" Text="Select" PostBackUrl="~/Orders.aspx" />

2) Use "RedirectUrl" in an event handler:
<asp:LinkButton ID="LinkButton1" runat="server" Text="Select" OnClick="LinkButton1_Click" />
protected void LinkButton1_Click(object sender, EventArgs e) {
Response.Redirect("~/Orders.aspx"); }

In both cases the browser's address bar shows [URL] without the QueryString, as I like to have it. But in the first case the page does not change at all. But it should, because I'm evaluating the QueryString in code-behind and control the appearance of the page depending on whether a QueryString exists or not. The second option works as intended. If I am not wrong the second option requires an additional roundtrip:

Browser sends request to server
Event handler on server side sends Redirect URL to browser
Browser sends again request to the server, but with the new URL
Server sends new requested page to browser

Whereas the first option omits the first two steps in the list above, thus saving the additional roundtrip and resulting in: Browser sends request to the server, but with the new URL (the PostbackURL specified in the LinkButton) Server sends new requested page to browser. Do I really need this second roundtrip of option (2) to achieve what I want?

How To Extract An ID Without Querystring Or Event Trigger Buttons

Feb 11, 2009 03:10 PM

I used a formview to display one record and lists its documents underneath based on its ID . So there are two table joins. One table for display main information and other its documents. I wrote a query Top1 statement to get the main information of the record displayed but How do I list its documents without calling a querystring and or any other event trigger button?

Here is my Example



As you can see from the code, in the page load I'm hardcoding an editionID to list its sub documents but how do I extract top 1editionID from the form view and list the documents on Page load. Or any other way I can display the main record and list its sub documents on pageload.?

But issue comes up when entering a value in the textbox and directly clicking on the save button without tabbing out of the text box. In the second scenario, only textchanged event fires and save click event dosen't fire. What I was expecting was after exection of textchanged event, save click event should also fire.

Web Forms :: Passing 2 Parameters On A Buttonclick Event?

Sep 08, 2009 02:13 AM

I want to pass 2 parameters on a buttonclick event, then use those parameters in code. But I seem to be unable to get the button to use CommandEventArgs.

Right now the code for the button says "Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs" and but that produces an eventarg of "System.EventArgs" rather than the commandargument specified in the button.

I tried changing it to CommandEventArgs but that produces an error of "Unable to cast object of type 'System.EventArgs' to type 'System.Web.UI.WebControls.CommandEventArgs'."

What I wanted to do was pass a commandargument of "p,FileUpload1" on the button click event and my code would use that information. I had planned on splitting the CommandArgument to get the two parts.

So how do I pass a string as the CommandArgument on the Button_Click event?
