Web Forms :: FileUpload Fails Despite Increasing HTTPRuntime MaxRequestLength?
Mar 21, 2010
I have an application (asp.net 3.5) that uses a fileUpload control. I have the entry in web.config set to:
<httpRuntime executionTimeout="3600" maxRequestLength="2097151/>
If I try a large file upload (around 20M), I get the "Internet Explorer cannot display the webpage" error. This code worked on another server and works locally, but when put on a new web host's server, I am getting this error all of a sudden. Is there any way I can get more information as to the cause of the error? I set my browser to uncheck "Show friendly http error messages", but I don't get more information.

Let's say you set maxRequestLength to the max number (2097151) (units are KB) and use the following code for your OnClick event for your submit button:
int int fileSize = FileUpload1.PostedFile.ContentLength;
if (fileSize < 2000000)//units are bytes
Label1.Text="too big";
else
{
FileUpload1.SaveAs(saveItHerePath);
Label1.Text = "Upload success.";
}
Why when a huge file is attempted does it take a minute to get to the OnClick event on the server? Because if maxRequestLength were set to that value 2000, it would immediately choke if you tried to upload a 500MB file. What is going on here? What are the best practices for using the FileUpload control? Is there a better alternative way of uploading or checking for file size?

Code:
<system.web>
<httpRuntime maxRequestLength ="1"/>
Above I have set the maxRequestLength to 1, it means i can upload the file upto 1024 MB.
Suppose I want that the user cannot upload the files greater than 4 MB.
Then 4 MB = .00390 KB
How to get above decimal value in maxRequestLength???

To me this should be much easier, but I can't seem to retain the values that are put in the Insert template upon a validation failure or when the sql fails. This will prevent the user from having to retype everything agin in the event of a failure.
As you can see I am using the Sub Insert_Click and not using an insert through the wizard. so the fields are unbound textboxes on the form. There are 2 dropdowns that provide choices for the other fields.
I pasted in the code using the text only option becuase the format was getting messed up. I probably need more background on why the fields are blanking out.

I am limiting file size users can upload to the site from Web.config. As explained here, it should throw a ConfigurationErrorsException if size is not accepted. I tried to catch it from the action method or controller for upload requests but no luck. Connection is resetted and I can't get it to show an error page.
I tried catching it in BeginRequest event but no matter what I do the exception is unhandled.
Here's the code:
protected void Application_BeginRequest(Object sender, EventArgs e)
{
HttpContext context = ((HttpApplication)sender).Context;
try
{
if (context.Request.ContentLength > maxRequestLength)
{
[Code].....
But I still get this:
Maximum request length exceeded.
Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Web.HttpException: Maximum request length exceeded.
Source Error:
An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.
Update:
What method raises the exception anyway? If I read the request it raises exception If I don't read it at all, I get "101 Connection Reset" in browser. What can be done here?

I have a file upload control on my page. The maximum request length set is 8 MB (maxRequestLength = 8192). I also have server validation that throws an error if the file is more than 4MB. The reason that its 8MB in the config is the leverage that's given to the user and also that the app can be tested.
If I upload a file that's 9MB, I get thrown an exception "Maximum request length exceeded.", which is fine and as expected.
But when I try to upload a file that's 1GB, it shows me a HTTP 404 - File not found. how can I get it throw me a maxRequestLength exception?
I'm using IIS6.

I have an ASP.NET AJAX autocomplete extender with CompletionListCssClass=autocomplete_completionListElement :
.autocomplete_completionListElement
{
width:500px;
margin : 0px!important;
background-color : inherit;
color : windowtext;
border : buttonshadow;
border-width : 1px;
border-style : solid;
overflow :auto;
height : 200px;
text-align : left;
}
But for some odd reason the width of the auto complete list always takes up the width of the textbox even when I set the width to 500px.

I've got a loop that executes the stored procedure in a loop with over 40,000 iterations, like so:
SqlCommand command = new SqlCommand("WriteDataToDB");
command.Connection = _connection;
command.CommandType = CommandType.StoredProcedure;
command.Parameters.Add("@SignalID", SqlDbType.Int).Value = Arg_Signal.SignalID;
command.Parameters.Add("@SignalStrength", SqlDbType.Float).Value = Arg_Signal.SignalSiggestion;
command.Parameters.Add("@Time", SqlDbType.BigInt).Value = Arg_Signal.TimeWasHit;
command.Parameters.Add("@Value", SqlDbType.Float).Value = Arg_Signal.ValueWasHit;
if (command.Connection.State != ConnectionState.Open)
{
command.Connection.Open();
}
command.ExecuteNonQuery();
This code is called from a loop where I intercept and time every 1000th iteration. The times I get are below:
[0]: "Started 0ms"
[1]: "1000 done 578.125ms"
[2]: "1000 done 921.875ms"
[3]: "1000 done 1328.125m"
[4]: "1000 done 1734.375ms"
[5]: "1000 done 1140.625ms"
[6]: "1000 done 1250ms"
[7]: "1000 done 1703.125ms"
[8]: "1000 done 1718.75ms"...........................

I have recently moved our ASP.NET session state from InProc to a Sql Server solution. I can see session data being inserted into the Sql Server database. I'm monitoring the w3wp.exe process using the "Private bytes" & "# Bytes in all heaps" performance counters.As I navigate through the website it places data into session, however the private bytes counter still climbs on the server hosting the website? I thought the session data was being written to the database and not being stored in memory? The managed bytes remain constant, and I'm pretty sure all the objects going into the session are managed types.

I have a website setup like this:
/Web --this is the client facing site /Web/Admin --this is the backend system and is setup as a Virtual Application
I'm using HttpRuntime.Cache for caching calls to the database. What I want to be able to do is clear something that is cached on the /Web site from the /Web/Admin site. It appears though that HttpRuntime.Cache is a single instance per application.

I have a SharePoint 2010 Farm and want to use object caching for my own custom objects.
Since it's an ASP.net Application at it's core, I could use HttpRuntime.Cache. On the other hand, SharePoint 2010 offers it's own SPCache.
Why would I choose SPCache over the HttpRuntime.Cache one?

I am new in Asp.net MVC but i really like it. I always prefer flexible authentication systems, on the other hand security is very important issue too. So i looked for some sipmle way to store current loged "user id/user name" in server side. I think that "HttpRuntime.Cache" can be a answer. So i write simple test project Of course this code is is not complete.

I'm working on Windows 2008R2 with IIS 7.5. In web.config there is config value:
[Code]....
Now, web request calls WCF service, which is very time consuming (timeouts for WCF are set to 5minutes). Whilst waiting for WCF to finish, web application throws exception:
[Code]....
As far as I make it out, it's exception caused by exceeding 90seconds limit. But... I get that exception after about 150seconds. Is it common that request doesn't break instantaneously?
I did some tests:
- set executionTimeout to 90seconds
- set WCF timeout to 500seconds
- play with Thread.Sleep in WCF service, and pass it a value between 90seconds and 500seconds.
It turned out that I got that
[Code]....
exception exactly after the time passed to Thread.Sleep method. Conclusion: web request thread has to wait for wcf call to return in order to be aborted?

We have a web application that is storiing all site data in HttpRuntime.Cache. We now need to deploy the application across 2 load balanced web servers. This being the case, each web server will have its own cache, which is not ideal because if a user requests data from webserver1 it will be cached, but there next request might go to webserver2, and the data that their previous request cached won't be available. Is it possible to use a shared-cache provider to share the HttpRuntime.Cache between the two web servers or to replecate the cache between them, so that the same cache will be available on both web servers?
