IIS Removes If-None-Match And If-Modified-Since Headers?
Mar 1, 2010
I have an ASHX handler or an ASPX page (the problem happens in both cases).
The web client sends a request containing If-None-Match and/or If-Modified-Since headers but context.Request.Headers.Get("If-None-Match") or context.Request.Headers.Get("If-Modified-Since") is null in the handler.
The same script works in my local development machine but it doesn't work in the online machine (both are running IIS7 on Win 2008, .NET 3.5)
The code has two ListBoxes in fact, one a "source" and the other a "destination". As you can tell above the ListBoxes are MyList_lstAll and MyList_lstSelected. These are rendered in the browser as <select> elements, as you'd expect.
The jQuery is working great, the items are moving from one ListBox to the other, the DOM is updated but when I submit this form (not using jQuery), the ListBoxes don't reflect this change on postback.
I realize my modifications via jQuery aren't available in ViewState but I thought since the DOM was updated these changes would be part of the postback data? But in the codebehind after postback the ListBox contents haven't changed. Does anyone know what might be going on and what I can do about it?
I have never work with a repeater and after a lot of research I got to the conclusion that this is the control I need to use for what I have to do. I need display data but I will need 2 headers and after some sort of amount of records the headers will repeat again. In this page you will find an example of what I'm trying to do http://ratings.fide.com/view_source.phtml?code=45276 I don't know if a repeater is the right control but i thin it is.
I have an AJAX NumericUpDown Control that takes a decimal. If I put in 1.30, it removes the zero. I do not want to remove the zero, it must remain at 1.30.
A demo of this can be found here: [URL]
For example, enter 1.30 in the text box then tab out or click somewhere else. The zero is removed.
I have some weird problem. We're using Windows Server 2008 R2 x64 (8 Cores and 8 GB RAM) with IIS 7.5 and ASP.NET MVC 2.
I always cache (simple) stuff via the context cache and it seems like 9 out of 10 immediate page refreshs the Cache["MyKey"] is always null, even though there's no memory limit set on the pool and the server has lots of free memory.
I add expiring data via:
[Code]....
When just doing: Cache.Insert("MyKey", myObject); or Cache["MyKey"] = myObject; I get the same result (cache is almost always null for that key).
As you can see I added a callback, which writes the CacheItemRemovedReason to a text file, and the text file says CacheItemRemovedReason.Removed for MyKey. The doc for CacheItemRemovedReason.Removed says, that I call Remove/Insert on it, even though in my whole project there's no "Remove"-calls, just simple if(Cache["MyKey"] == null) {Cache["MyKey"] = ...} stuff.
I haven't been able to find relevant information through searches. I'm very green when it comes to sever side scripting. I have an ASPX page with a standard form. In the head I have meta tags, the title tag, and a link tag neatly ordered on their own lines. However, when viewing the source code after publishing to the server, the spacing between the tags is removed and it looks quite messy. (There are also <style> and <script> tags that follow, but they remain unaffected.)
I realize this has no practical effect on the site itself (in an SEO sense or otherwise). My project manager shows the source code to our clients to educate them on meta tags and page titles. It would help if it wouldn't become jumbled like this. I wonder if this is a common issue and if it's possible to prevent through better coding practices. HTML as authored, with tags separated on their own lines:
HTML Code:
<head runat="server"> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <meta name="description" content="Welcome to Lawn Care Waukesha - Cut My Lawn. Cut My Lawn - Lawn Care Services has offered quality lawn cutting, fertilizing, aerating, and much more at affordable pricing since 2002! We currently offer lawn care service to Waukesha, Brookfield, Pewaukee, Menomonee Falls, and surrounding communities." /> <meta name="keywords" content="lawn cutting, lawn mowing, lawn care, fertilizing, aeration, mulching, shrub trimming, lawn mowing, edging, pruning, mulching, weed control, waukesha, Brookfield, Pewaukee, menomonee falls" /> <title>Lawn Care Waukesha — Cut My Lawn, Lawn Care Service</title> <link rel="shortcut icon" type="image/x-icon" href="favicon.ico" /> HTML after being processed by the sever, with all the tags running together:
HTML Code: <head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><meta name="description" content="Welcome to Lawn Care Waukesha - Cut My Lawn. Cut My Lawn - Lawn Care Services has offered quality lawn cutting, fertilizing, aerating, and much more at affordable pricing since 2002! We currently offer lawn care service to Waukesha, Brookfield, Pewaukee, Menomonee Falls, and surrounding communities." /><meta name="keywords" content="lawn cutting, lawn mowing, lawn care, fertilizing, aeration, mulching, shrub trimming, lawn mowing, edging, pruning, mulching, weed control, waukesha, Brookfield, Pewaukee, menomonee falls" /><title> Lawn Care Waukesha — Cut My Lawn, Lawn Care Service </title><link rel="shortcut icon" type="image/x-icon" href="favicon.ico" />
I'm not sure it's relevant, but here's the script used to send the form (which I didn't write, by the way). It's the final tag inside the page head:
HTML Code: <script type="" runat="server"> Protected Sub SubmitForm_Click(ByVal sender As Object, ByVal e As System.EventArgs) If Not Page.IsValid Then Exit Sub Dim SendResultsTo As String = "email" Dim smtpMailServer As String = "smtp" Dim smtpUsername As String = "email" Dim MailSubject As String = "subject" Try Dim txtQ As TextBox = Me.FormContent.FindControl("TextBoxQ") If txtQ IsNot Nothing Then Dim ans As String = ViewState("hf1") If ans.ToLower <> txtQ.Text.ToLower Or ans.ToUpper <> txtQ.Text.ToUpper Then Me.CutMyLawnForm.ActiveViewIndex = 3.......................
How to make a build in VS 2010 within an ASP.NET MVC application that would remove all of the source code (CS and VB) files? When I build a website or web app I usually copy the contents of the entire solution to the hosting server. Mostly clients get the source but sometimes I do not want to expose the source to the hosting server thus only the Public (or Content) folder, views, masters and the built DLL should be copied.
Manual solutions are not applicable. What do you guys use?
What I'm interested in is a regular expression that will accept HTML input and remove all attributes inside the tag while leaving the tag intact. For example I want this...
<p class="test" id="TestParagraph">This is some test text right here.</p>
I face this weird problem when I was trying to add multilanguage support to my website.The main login page contains user control and I am also using Master page. I added a linkbutton to master page so I can switch to other language from any page. So, whenever I want to switch langauage, I check this linkbutton text value. so I use this code
am using this function to remove whitespaces at html output. i had to put if else otherwise page was giving error afterasynchronous postbacks. now it works fine.is it possible to make it work also after asynchronous postbacks ?also is it possible to make this regex function also removes new lines ?like how google doesthere is no line at their source codes
EmptyDataTemplate and EmptyDataText not working in GridView
using CSS-Friendly Control Adapters removes the data that would would be populated by EmptyDataTemplate or specified in EmptyDataText in GridView. One of the solutions is to disable the addapters for GridView components as specified in this answer Is there a solution, that would allow to keep the use of CSS-Friendly Control Adapters for GridView and still take advantage of EmptyDataTemplate functionality?
I am creating an HTML document using HTML agility pack. I load a template file then append content to it. All of this works, but when I view the output file it has removed the closing tag from my <br/> tags to look like this <br>. What is causing this?
Dim doc As New HtmlDocument() doc.Load(Server.MapPath("Template.htm")) Dim title As HtmlNode = doc.DocumentNode.SelectSingleNode("//title") title.InnerHtml = title.InnerHtml & "CEU Classes" Dim topContent As HtmlAgilityPack.HtmlNode = doc.GetElementbyId("topContent") topContent.InnerHtml = html.ToString doc.OptionWriteEmptyNodes = True doc.Save(outputFileName, Encoding.UTF8)
More info:
It was removing my closing image tags, after I added doc.OptionWriteEmptyNodes = True, it quite doing that.
I have an updatepanel in my content page with a timer which re-renders the updatepanel every 5 seconds.I also have a textbox outside of this updatepanel in my masterpage.Whenever the timer ticks, focus is lost from my textbox. What possible reasons are there for this happening?
when I have <form> </form> tag on my .aspx page. then it cause some problem in page, for instance: I have header, which has one vertical line in it, but when I use form tage in page then all data is correct, but from the header it remove one verticle line.page with form tag in local environment (development environment) works fine, but when I move it to live then it creats problme.
I have two repeaters bound to object collections. They both work fine. But when I move repeater B to repeater A's FooterTemplate the serverside declaration of repeater B disappear.This is not a parent/child relation.
I'm new to .net, and I've noticed that when viewing my HTML source code generated by a .net application the carriage returns are removed from the head tag when it has runat="server" attribute on it.
I remove the runat="server" and the returns... return.
This really looks nasty when you have a few javascript and css files in your header because it ends up making the entire contents of the head tag 1 big line.
Just wondering if there's a way to control this or tell .net through configuration not to mangle the output?
Now i have a checkbox column in the gridview, and select all checkbox also, for functionality of checkboxes i am using javascript like what is explained by this article:Â [URL] ....
I like this way its simple and fast. but now when gridview refreshes the checkbox selection and others styles disappears.
Now what can i do to keep my selection as it is on gridview refresh. Do i have to stop the gridview refresh on checkbox selection?

I have added a datetime field to my db and added the default value binding to (getutcdate()), (allow null=false) how can I have the date/time added to my db when the user is adding his data ?
I'm trying to access the innerHTML of a span tag modified by jQuery using C#. This is my first project shunning the AJAX libs in favor of jQuery, so I'm not sure how I can get the codebehind to recognize the manipulated innerHTML. I've set all the spans I want to tap into with runat="server", but all I pull are the values I've set when the page was designed.
What steps should I be taking to enable communication between the client-side and my codebehind, and am I even using the best practice here?
