Request.QueryString[] That Contains '+'

Jul 31, 2010

I have a page that I wish to pass an ID in a querystring to another page

eg

Response.Redirect("~/Account/Login.aspx?CertificateID="+ CertificateTextBox.Text);

but the value in the CertificateTextBox is in the format of Encoding.UTF8

so it can contains character like "ZnbiS69F2g22OeupHw+Xlg=="

When the receiving page gets the QueryString

CertificateTextBox.Text = Request.QueryString["CertificateID"];

the "+" and possible other querystring chars like "?" are stripped!!

so I end up with

Request.QueryString["CertificateID"];

returning

"ZnbiS69F2g22OeupHw Xlg=="

the "+" strinpped!

Is there a way to encode these chars so they are not striped by QuesryString()or do I have to use a session variable??

HttpHandlers / Modules :: HttpModule That Alters Request.QueryString And Request.Form?

Jan 27, 2011

We're trying to implement functionality that intercepts, inspects, and alters if needed data in the Request.QueryString and Request.Form collections.

Since Request.QueryString and Request.Form are readonly, is it possible to use a HttpModule to do this without Reflection or Response.Redirect?

We're thinking that we can construct a new HttpRequest, and replace the original one. Would there be any implications in doing this?

I know mocking this object is impossible without using HttpRequestWrapper, but wasn't sure whether ASP.NET sets other things beyond the constructor.

No Querystring Logged In IIS Log On "A Potentially Dangerous Request.QueryString Value Detected"

Mar 5, 2010

I'm intermittently seeing this exception being thrown:

A potentially dangerous Request.QueryString value detected

However when I look in the IIS logs I can see that the request that failed has no querystring logged against it.

How could this be? Are "dangerous" query strings being stripped from the log or something?

Getting QueryString From Request Or Javascript?

Jan 19, 2010

In aspx I have a querystring - www.mysite.com/enter.aspx?dest=#. When I click "enter" I go to main.aspx. I want to get this "?dest=#" in main.aspx with a request.querystring or something in javascript. I need to use the querystring in javascript in main.aspx for another action.

let me explain in detail - I have enter.aspx page that shall load with a querystring - www.mysite.com/enter.aspx?dest=#. Now when i click the Enter button on Enter.aspx page, it shall goto Main.aspx page. When main.aspx page loads i want to write small javascript in main.aspx that shall get the querystring from the previous enter.aspx page and give it an if condition. so if (request.querystring('dest=') > 0 window.open ('a1.jpg') this above code needs to be redesigned so it can work. how can i do this. i tried window.location.href.indexof('dest') , nothing happened.

Request.Querystring And UrlDecoding?

May 20, 2010

(asp.net 2.0, c#) I have a page requesting a qyerystring looking like this ?test=b%E4st, %E4 is the url-encoded letter ä. I can't change how this looks and encodes since I have no access to the page doing the request.

Problem: string strTest = Request.Querystring["test"].ToString();

If I then, for instance, just Response.Write(strTest) the character ä (%E4) is broken. Displayed as a question mark. I have in my web.config the requestEncoding and responseEncoding set to utf-8. That is the way I need to have it, and I can't change that.

I've looked around for a solutions for this and the issue seems to be iso-8859-1 vs utf-8 in the querystring and url-decoding. It seems the Request.Querystring automatically url-decodes the string using the default encoding, in my case utf-8. I need it to url-decode using iso-8859-1 instead. I can achieve this by altering the web.config, but as I said earlier this is not an option.

I have tried to do this:

Encoding enc = Encoding.GetEncoding(28591);
string strTest= Request.QueryString["test"];
strTest= HttpUtility.UrlDecode(strTest, enc);

Not working, since the Request.QueryString already has url-decoded the value using utf-8.

Request Querystring - Can't Figure Out Syntax

Dec 19, 2010

I'm passing a variable between pages and want to print the value of the variable on my page and don't particularly want to try to get into figuring out the codebehind stuff. I can't figure out the syntax. I'm trying:

Page Title="" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="WebForm2.aspx.cs" Inherits="WebApplication2.WebForm2" %>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
<script runat="server">
Request.Querystring("letter")
</script>

I know I'm passing the variable correctly because it works in a query further down the page, so I suspect I'm just not using Querystring right.

Web Forms :: Request.QueryString Not Decoding URL?

Nov 1, 2010

I have vendors who are passing customers to us via an encoded URL. The problem is that Request.QueryString["FieldName"] is returning NULL on some of them and I can't fiqure out why?

For Example, one vendor is sending : http://.....ViewListing.aspx%3FListingID%3D1187721%26Source%3D6"] which returns a NULL value when Request.QueryString["ListingID"] is used.

Using Server.UrlDecode(Request.RawUrl.ToString()), however, will decode itpProperly as /ViewListing.aspx?ListingID=1187721&Source=6

How do I get the Request object to properly retrieve the values?

Web Forms :: Request.Querystring Isn't UrlDecoding?

Apr 15, 2010

Anyone else have the issue where you use javascript to stuff variables into the querystring and then when you call Request.Querystring, the value is still UrlEncoded?Example, I've used a javascript function to encode the string "dBskf6fm+ac=" into the UrlEncoded string "dBskf6fm%2Bac%3D".Usually when I set a breakpoint at the call to Request.Querystring(), the value displayed is the UrlDecoded string, but in this case, the value is still UrlEncoded.

Web Forms :: Request.QueryString Doesn't Get The Original Value?

Jan 28, 2011

When I pass some values like a++, c++, f+, as a parameter value in the url to an aspx page, I don't get the exact value in the aspx.cs page by Request.QueryString function. This problem is only with some special characters like +, _ , - etc.

Eg:

Consider this parameter string in the url : CourseName=c++&kval=0.7120968615801844&dval=1296217545373

Then when I trying to get the CourseName parameter value in the aspx.cs page using
Request.QueryString ,

crseName = Request.QueryString["CourseName "];

I got the value of the variable crseName as " c " only instead of "c++ "....

AJAX :: Control Toolkit Clearing Request.QueryString?

2) User clicks next on form 4, and form 4 checks the query string that was passed by 3, and it's emtpy

This only happened when I added AJAX functionality.

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

Apr 6, 2010

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:

/somepage.aspx
/somepage.aspx?valueOfInterest=sausages

would become:

/somepage.aspx?valueOfInterest=wibble

And most importantly (perhaps) a request for:

/somepage.aspx?boring=something
/somepage.aspx?boring=something&valueOfInterest=sausages

would preserve the boring params to become:

/somepage.aspx?boring=something&valueOfInterest=wibble

Caveats: I'd like to avoid string manipulation if there's something more elegant in asp.net 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
