.NET/IIS6 - Disable Chunked Encoding When Using Dynamically Compressed Content?
Oct 7, 2010
I'm running ASP.NET on an IIS6 server. Right now the server is set up to compress dynamically generated content, mainly to reduce the page size of ASPX files that are being retrieved.
Once of the ASPX files has the following bit of code, used to fetch a file from the database and send it to the user:
The download itself works perfectly. However, the person downloading the file doesn't get a progress bar, which is incredibly annoying.
From what research I've been doing, it seems that when IIS sets the transfer-encoding to chunked when compressing dynamic content, which removes the content-length header as it violates the HTTP1.1 standard when doing that.
What's the best way to get around this without turning dynamic compression off at the server level? Is there a way through ASP.NET to programatically turn off compression for this response? Is there a better way to go about doing things?
I'm trying to create a HttpModule that changes the Response.Filter like so(for this demonstration just set the filter back to itself):
public class ContentTrafficMonitor : IHttpModule { public void Init( HttpApplication context ) { context.BeginRequest += OnBeginRequest;[code]....
Doing so sets the transfer encoding of the response to chunked, rather than using the Content-Length header.If I remove the line where the Response.Filter is set, the response does have the Content-Length header. Our application depends on the Content-Length header, is there any way to prevent this behavior?
I have written a web mailer that can send and receive emails and display them on a webpage.I have a problem displaying special characters though. Like Russian, and Greek and chinese.I am using openpop.net and I can get the encoding of the incoming email as one of my variables.Thing is, how do I display it? Do I set the content encoding of the whole page to what that specific email encoding is?I've got it UTF-8 at the moment and I get garbage.
I have an HttpModule which is used to dynamically compress content from an ASP.NET (MVC3) web application. The approach is very similar to the CompressionModule in this article (where the module applies a GZip filter to the HttpResponse and sets the correct Content-encoding header).For one reason and another, this needs to run in classic mode, not integrated pipeline mode.
The problem I've got, is that on some servers that have IIS compression enabled, IIS compresses the content and then my module compresses that. The upshot is that I get content compressed twice, with an encoding:
Content-encoding: gzip,gzip one from IIS, and one from this line in my code:
Does anyone know a way, in classic mode, that I can check to see if the content is already compressed, or if compression is enabled on the server, in order to bypass my own compression?In pipeline mode, this check is as simple as
if (httpResponse.Headers["Content-encoding"]!= null) { return; }
i.e. check if anything has already set a content-encoding and if so, do nothing.However, I'm stumped in classic mode. Unfortunately, accessing HttpResponse.Headers is not allowed in classic mode, so I can't do my barrier check.
I have discovered that the NavigateUrl is encoding the URL when it render it. It is a bit of a problem for me in Denmark because we have domianname with special charters. ex. [URL] the hyperlink control render it like [URL]
i have a ASP.NET 4.0 based CMS, where i use the TinyMCE (3.4) via jQuery to edit one Textbox.In addition to this i have several other textboxes. There is also another DropDown List on the Page, which controls the Contenttype.This Control has AutoPostback enabled and sets the visibility on the textboxes regarding the selectes item.As i want to keep the Postback Validation on i have configured the TinyXML to use xml for the content serialisation (encoding: "xml").Now i have the problem, when a postback from e.g. the DropDown List occures, the re-encodes the content.
i have enabled the original textarea via css and this seems to be a problem of the TinyMCS's Save method. Does anybody have a solution, how to fix this issue maybe with a custom save_callback on the TinyMCE?
We have a ASP.net form [.NET 3.5 on IIS 6] that loads controls dynamically. We are able to retain the values in the viewstate as long as the postback happens within 20 minutes. The database also gets updated properly. Everything works as expected.
However, If it takes more than 20 minutes for a user to fill out the form, the controls no longer retain their values during postbacks. The session values are intact, the user authentication is also intact. We tried several things
1) Added machine keys to web.config files - we have 2 web servers load balanced by Windows load balancer
2) We confirmed that the user are routed to the same server - because the sessions are sticky
3) Increased the session timeout to 60 minutes in IIS 6.0
4) Increased the Idle timeout for connection pool to 60 minutes
5) Changed Form authentication ticket timeout to 60 minutes
In my vague understanding, any texts are transferred over the internet as streams of bytes. And when you change texts to and from bytes, you need encoding. MailMessage.Body is just a plain string(text) and it gets sent over the internet as emails. Why is it that it can correctly display Chinese characters without even having to specify the encoding?
I will be getting data through wcf service coming form commerce server (instead of DB). Data which is coming will be in the form big html content with all html tags or may be a single line sentence. I should display this dynamic data into the placeholder in the content page (master content page). I have been trying but not able to load when the data is in the form of HTML page. html content or may be single lline of senetence.
Im pulling out a text field from the database which has and 's in it for line breaks. Which I have left there for pupose of being able to edit the fields later on.
So when i try to display the text I need to replace them which I have done with:
[Code]....
Simple enough. Only when I run the page the source code I get for it is:
<br />
So it seems its not encoding the < as a encode but into the form <
Does anyone know how to stop this happen. Or a method around it?
For an ASP.NET 4.0 / IIS7 web app, I would like to support compressed HTTP requests. Basically, I would like to support clients that would add Content-Encoding: gzip in the request headers, and compress the body accordingly.
I've seen a number of options for adding GZIP/DEFLATE compression to ASP.Net MVC output, but they all seem to apply the compression on-the-fly.. thus do not take advange of caching the compressed content.
Any solutions for enabling caching of the compressed page output? Preferably in the code, so that the MVC code can check if the page has changed, and ship out the precompressed cached content if not.
This question really could apply to regular asp.net as well.
I'm making a asp.net web project using visual web developer 2010. I want to use ajax control toolkit so I have dowloaded the compressed folder and I added a tab in my project with all the ajax control toolkit. The problem is when I try to run the project it gives me the following message: " It's impossible to find the file 'd:hgactServerAjaxControlToolkitExtenderBaseExtenderControlBase.cs'.
After an Internet researcj , I supposed that this error is caused by the fact that I created a simple web project, while I had to create a ajax web toolkit project. The question is:how can I create it?? In the home page of visual web developer 2010 the model "ajax control toolkit web site" doesn't appair in the installed models!! How can I import it, or can I solve this problem in general?
Is it true that it has been originated that the fact I created a simple web project instead of a ajax control toolkit project?
I'm trying to have a checkbox disable and enable a textbox, within a strongly typed viewmodel.
[Code]....
I couldn't find any way to make a checking the nine2five checkbox to disable the startTime and endTime textboxes (and set values to 9 and 5 appropriately).
I have a webpage that inherits a masterpage. Within the webpage I have the content palceholder and then a table within that that contains all the controls of the page. Like below:
[Code]....
I want to be able to change the fields to readonly if a field in the database for the user says they should have readonly access. I can't seem to find the level to go to in order to loop through the controls of the page to set their access to readonly.
I have gotten down to this level and it seems like it is in the base of this.
I'm fairly new to jQuery and I've been looking for a decent free datepicker for a while now. I am quite satisfied with jQuery UI's datepicker but I've hit a snag. The project where I'm using this requires that I have an icon beside the textbox. While this is fairly easy, I don't know how to dynamically disable the icon. There are two things I'm interested in knowing:
How can I dynamically change the disabled status of the datepicker from code-behind so that it triggers on postback? Is it possible to make it's disabled status dependent on the textbox that it is attached to? (i.e. if
<asp:TextBox Id="txtMyTextBox" Enabled="false">
then datepicker gets disabled as well.
This is the code I've been using for the datepicker.
I have an application that is supposed to accept checks. The user has 2 radio buttons. The first radio button has a drop down list associated with it which contains the masked numbers of their previously used checking accounts.
The second radio button has three text boxes and an image of a check associated with it.
When a user hits this page, the three text boxes and the check image associated with the second radio button are disabled. Then, if the user decides he/she wants to use a new checking account, they can click the second radio button and that fires the Javascript that enables the three check boxes and the image of the check associated with that second radio button. If they click on the first radio button, it will re-disable the text boxes and hide the check image associated with the second radio button.
The problem happens when I do my server side validation. After validating all text fields, if there is a problem, I just fall out of the bottom of the code, the page posts back and the labels above the offending text fields show an error message.
One caveat: The Javascript that is supposed to fire on the OnClick event for the first radio button fires and the text fields for the second radio button are disabled. The user can click on the second radio button and the fields will enable, but this is very clunky.
Here's the enable code where I am injecting the Javascript:
Private Sub JavascriptInject() Dim sEnableControls As String Dim sDisableControls As String
Is it possible to make some of the AccordionPanes disabled dynamically from server side ? So that the header not clickable and the accordion content is not visible?
I am working with a few .Net 4.0 webforms controls such as the Menu control and while I think it's great that I can now declare the way in which controls are rendered (i.e. as either tables or divs), I can't switch off the automagically-included javascript that manages the hover events for those controls, for example:new Sys.WebForms.Menu({ element: 'NavigationMenu', disappearAfter: 500, orientation: 'horizontal', tabIndex: 0, disabled: false }This appears at the bottom of every page that owns such a control.
