I'm trying to serve a pdf file from a database in ASP.NET using an Http Handler, but every time I go to the page I get an error
XML Parsing Error: no element found

We have a large site with thousands of static html files. Some of them are ISO-8859-1, others are UTF-8 (with and without byte order marks).
The web.config file looks like this:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.web>
<globalization requestEncoding="utf-8" responseEncoding="utf-8" fileEncoding="utf-8" />
</system.web>
</configuration>
If I change the fileEncoding to "ISO-8859-1" it works for both ISO-8859-1 and UTF-8 if there is a byte order mark. We are trying to avoid manually checking and adding byte order marks to files that do not have them. Is there any way to accomplish this?
The files have the charset meta tag. Can we make the server read that to determine the file encoding?
EDIT
If I remove the wildcard application mapping to aspnet_isapi.dll the files are served correctly. Is there any way to have the wildcard match everything except for .html?
I am hosting the ASP.Net runtime in my exe but I find that if I try to access htm or xml files from the browser, it gives a 404.
I can access aspx, asmx and other asp.net related files just fine.
Is there any configuration that I need to do to server other file extensions and if so, what?
I am working on a web application where images has to be scaled dynamically and served to the client as fast as possible (with low overhead). I need to create something that scales and compresses high-quality PNGs to medium quality JPEGs.Now, there are multiple ways of doing this and I am slightly confused which method provides the best solution for the application to be as fast as possible - and I was hoping you guys could guide me in the right direction.This application will run on the .NET 3.5-platform and I am looking for fresh ways of doing this. Googling has given me some clues but most of the articles I found were VERY old (2000-2005 or so).The client app is written in ASP.NET MVC, while the backend app is written in Web Forms. The images are located in a directory in the Web Forms application, but I guess that dosen't say the image handler must be written in Web forms.

But this keeps timing out after few request. I have looked into the IIS worker process requests and I can see the requests being in there in the state of sendresponce. If I request the same url from my browser the reponce is there. Am I doing something wrong here?
I am new to IIS and asp and i am having a problem. I am creating a asp.net website in physical folder wwwrootSharePage and virtual directory SharePage When i visit the site on local host or using my ip address or through dyndns proxy on my own computer , the page is served fine, But when any one else from any other computer access my website it takes a long time in loading and finally his browser throws an error (may be page not found error,not sure, see for yourself). I have even changed Authentication mode to none and tried with firewalls closed , still page is not served.

The app_offline.htm file that ASP.NET serves returns the http status 503. This is the correct behavior for most situations. However, in the scenario where a specific URL is requested (e.g. [URL]), I'd like to change the returned http status to 200, while still returning http status 503 in all other situations. Is this possible?
The reason why I want to do this is whenever we do scheduled maintenance on our website, we use the app_offline.htm file, but we don't want our uptime monitoring service [URL] to report downtime during our scheduled maintenance.
I assume this would have to be at the IIS level because the app_offline.htm gets served very early on in the request processing cycle.
I have a domain which is receiving quite a few hits per day and have been asked if I can serve the static content from a subdomain. As the site is quite extensive and already written, I was wondering if there is any way I can use URL rewriting to change:
www.example.com/image.gif
to
static.example.com/image.gif
I have a solution which works using 301 redirects but from what I understand, this is counter productive as 2 requests will have to be made per image. I don't really want to go through all the aspx pages and css to hard code the new url as it will cause problems further down the line - some parts of the site are still being developed and static content could change at any time. I tried using rewrite (as opposed to redirect) to change the url but it came out something like:
http://www.example.com/http://static.example.com/image.gif
How would you achieve this? I have full access to dns and the server (win 2008r2 / IIS 7.5) so can make any changes if url rewriting is not the answer.

My WebApp is part CMS, and when I serve up an HTML page to the user it typically contains relative paths in a.href and img.src attributes. I currently have them accessed by urls like: ~/get-data.aspx/instance/user/page.html -- where instance indicates the particular instance for the report and "user/page.html" is a path created by an external application that generates the content. This works pretty reliably with code in the application's BeginRequest method that translates the text after ".aspx" into a query string, then uses Context.RewritePath(). So far so good, but I've just tripped over something that took me by surprise: it appears that if any of the query string ("instance/user/page.html") happens to contain a plus sign ("+") the BeginRequest method is never called, and a 404 is immediately returned to the user.
So my question is two-fold:
Am I correct in my belief that a "+" would cause the 404, and if so are there other things that could cause similar problems? Is there a way around that problem (perhaps a different method than BeginRequest)? Is there a better way to preserve relative URL paths for generated content than what I'm using? I'd rather not require site admins to install a 3rd party rewrite tool if I can help it.
I'm busy writing a handler to serve various documents for download or presentation in web forms pages. The documents range from various image formats, to PDF, to MS Office documents, to generic binaries. My basic draft of the download process is as below:
[code]....
However, I have some misgivings about lumping all documents together as application/octet-stream, and I would prefer, if feasible, to use a more specific content type per document type. I have a DB table for document types where I could store this. Am I going in the right direction, and if so, where can I find a suitable starting list of content types for document types?
I have a project that will be assigned to me soon whereby I need to develop a survey which needs to support 40,000 users approximately. Now we are thinking of doing a staged approach so not all users are on the server at any one point of time. Probably splitting it so we can serve at least a few thousand of users...
I dont have much experience of how I can ensure to serve those levels of users on a server and how to manage this so I am after some advice?
From my understanding I need to do some stress testing on a server and obviously I need some figures i.e. average size of request, average size of response and content of response.
- Do I have to build the database and add records in to see what size is a typical survey row?
- Do I have to build the survey in .NET i.e. by adding controls etc and seeing what size is the page?
- The survey shouldnt be too instensive processing wise, it will be adding information into a backend sql database...
I have a scenario where...
1.) Have created a div with a dropdown list and ok, cancel button
2.) On document ready - registering div created on step 1 into a jQuery dialog
3.) on a javascript button click - I am opening this dialog box.
4.) Now, the problem is - the jQuery dialogbox which I have created, needs to be used by other button clicks as well on same page. Now, my div's (which is a dialog at runtime using jQuery) ok button click is already engaged with a javascript function (button1 click) and I can not associate other button's click events with it - thus stuck up here and have no clues or hit to resolve this.
What ASP.NET page lifecycle event can I write code in to determine the size of the viewstate that being sent out? Also, is it possible to determine the size without parsing through the rendered HTML (like a property on the page object) or is parsing the only way?
What I'd like to do is log the sizes, specifically if they cross a certain threshold.
I'm trying to server an exe to Firefox from an aspx page. The aspx page handles the headers and the page is launched by our Flex GUI. Flex correctly launches the link for all browsers (including Firefox) so I'm certain that's not the issue.
The problem I'm having is when I try to download the file from within Firefox, FF downloads the file fine but it names it "Content". It has no extension and the file name is incorrect. All the other browsers download it with the file name I specified in the aspx page and they all have the .exe extension. I should note that if I rename the "Content" file to "Content.exe" it runs correctly.Below is the code I'm using in my aspx page -
protected void Page_Load(object sender, EventArgs e) {
string fileName = Request.QueryString["file"];
System.IO.FileInfo fileInfo = new System.IO.FileInfo(Server.MapPath(fileName));

I have a serious problem with "Error on Page". The error message points to line number 939, char 13. In my code behind (C#) in line number 939 is only an obsolete method found which is no longer called. The aspx file has only 339 lines. What the heck is line number 939?The Webapplication allows a special user group to change some group memberships for members of another user group in Active Directory. The App handles 3internal DataViews derived from corresponding DataTables as DataSource for 3 GridViews and some other internal lists with objects (List<obj>).
It uses windows authentication to get current users credentials and his membership in the "Operators" group. This credentials will be passed-through to allow the process managing group memberships in active directory.After starting the App in browser it seems to work fine. But after an indeterminated time it doesn't longer respond. After each click on buttons (or link buttons) you only can see the message "Error on Page" in the browsers status bar below.I played with session timeout, storing the DataTables in session variables, without success.
Last week I found this article here: [URL]" and I addedEnableEventValidation="false" ViewStateEncryptionMode="Never"
to Page declaration. However, at some point the the server does not respond. Each time the worker process on webserver recycles it seems the application turn to wrong state. Might be important: All controls including GridViews are embedded in an AJAX UpdatePanel. How to get a better error message? Debugging is enabled and Custom Error handling On, Off or Remote Only brings the same result as described.
When a server error occurs for whatever reasons (YSOD), the server will send a message via SMTP class. In my case, my company employs microsoft exchange and uses NTLM authentication for all domain users. I am authenticating users via NTLA windows integrated authentication. My question is, is it possible to utilize this authentication data, and pass it to the system.web SMTP username/password authentication scheme to send an email to me (the web developer) when the error occurs? I am pretty sure my company requires a username/pwd to send emails via SMPT on the ms exchange server.
