I have a web application in asp.net and C# that must access a remote server to copy some files. The web application basically deploys other web applications. Let us say that the web app runs on a "developement" server and needs to interact with a "production" server. From the user's point of view they are both remote machines. He accesses the application (running on the "developement" machine) on his browser and does not see the code and the access credentials to the "production" machine

I know that ASP.NET MVC has error filter attribute to handle specified error type. However, this feature cannot catch any error that occurs when application start. Therefore, I need to add some code to "Application_Error" method for handling this error like the following code.
public void Application_Error(object sender, EventArgs e) {// At this point we have information about the error var ctx = HttpContext.Current; var exception = ctx.Server.GetLastError(); [code]...

i am new in asp.net. i have create a website. its related to tours and travels. Now when any customer get login to webportal then the login info of that customer should send to my system i.e. website. here it will check the user is valid or not or new according to that check user's permissions and send the data to the webportal.
then customer can search the specific data and book the some data say 'hotel'. that time the booking information should send to back to the system. so my query is how can i send the information from my system to webportal and vice versa...(can i do it with javascript)
I have a class which implements IHttpHandler that is designed to handle image resize requests. It handles Urls like so [URL] Currently the handler looks for myimg.jpg on disk, cuts a 100x100 thumbnail (if it isn't already present) and redirects the client to the thumbnail like so Response.RedirectPermanent("/some/virtualPath/to/thumbnail.jpg");
This has been working great, but I would like to avoid forcing the client to issue a second HTTP request. Is it safe to do the following? Server.Transfer("/some/virtualPath/to/thumbnail.jpg") All the MSDN documentation talks about using Server.Transfer() to redirect to an aspx page, so I'm not sure if this is the right thing to do or not.
I would like to be able to give my users the ability to securely upload and store files, sometimes upwards to about a gigabyte in size. I'm not quite sure what's the best way to go about doing this. I would like to have the connection between the client and the server secured, so I'm sure I will probably have to use SSL. Now, my major crux is secure storage. Being that the data is somewhat sensitive, I'm wondering if I should encrypt the file before it is stored. I guess my question is, should I open the file and encrypt each byte or encrypt the file as a whole. I'm assuming that the latter is the better option. I know that there are a number of examples of how to encrypt a file using a number of different methods (aes, des, md5 (hashing not really encrypting), etc). Currently, to encrypt text, I am using the Rijndael algorithm, sha1, 256 bit keys, a predefined passphrase, salt value, and IV.
When I tried to send file to the URI stated above, the server throw the status 400 back to me when I tried to get the response from the server, and the https server doesn't receive any file. While I changed the URI to point to another server, which is a http server, the code works fine and able to send file to the server. I would like to know why the code above is not able to send the file to the https server?
I´m making a gridview with a sql query where I also do an upload to an FTP address for each column. It works and several files are being send but after 2 minutes I got "the operation has timed out". I have tried setting this in the web.config but it does not solve it:
httpRuntime maxRequestLength="6024000"
What can I possible to? Is the page timing out due to the sql connection or just the webpage request?

How to allow the users to transfer files to web servers from their local machine?
Our website runs on ASP.NET v4 and users log in user Forms authentication.
We are considering purchasing a web application that will add to our services. The only problem is that this new website is written in PHP.
We would like users to login to our ASP.NET site and then navigate to the PHP site. The PHP site should notice that users are logged-in though. So we probably need to transfer the ASP.NET SessionID cookie and somehow use that to verify whether or not the user has been authorized.
Here is 2 web applications: 1 is asp.net, another is J2EE base webapplication.Both them are using same AD ( e.g. DomainTest ) as authentication source.Question here:1. User log in the asp.net application ( form based log in DomainTest, not IE prompt authencation dialog ), on the left navigation ( link to J2EE web application), just click this link, SSO to J2EE application.I think should transfer identity token from asp.net to J2EE, but don't know how, and for JSP, how to modify it to use token tranferd from asp.net ?
i have two application suppose wwwroot/one and wwwroot/two.
there is one .aspx page on "one" application into which i want to get file(.xml) from application "two" and do some work on that file like save,edit,delete etc..
and than save that file into "two" application.
like
wwwroot/one/MyFile.aspx --> this is file into which i want to access aaa.xml file from application two/File where File is a folder. all file operation is here.
wwwroot/two/File/aaa.xml --> this is xml file which is reside in another application
I am using JQuery & JSON (POST) to call webmethod. However I can call only webmethod located at aspx file but not in asmx file Below are sample codes
CustomValidate.asmx Imports System.Web.Services Imports System.Web.Services.Protocols Imports System.ComponentModel Public Class CustomValidate Inherits System.Web.Services.WebService 'ACCESS VIA JSON <System.Web.Services.WebMethod()> _ Public Shared Function AJAX_Test(ByVal date1) As Boolean... Return True End Function End Class Javascript: JQuery JSON function isDates(source, arguments) { var isValidDate; $.ajax({ type: "POST", contentType: "application/json; charset=utf-8", url: "CustomValidate.asmx/AJAX_Test", data: '{date1: "' + arguments.Value + '"}', dataType: "json", async: false, success: function(result) { isValidDate = result; }, error: function(httpRequest, textStatus, errorThrown) { alert("status=" + textStatus + ",error=" + errorThrown); } }); arguments.IsValid = isValidDate; }
It always return javascript undefined error. But if I put the AJAX_Test webmethod in aspx page and replace the url: "CustomValidate.asmx/AJAX_Test" to "mypage.aspx/AJAX_Test". It works fine.
I would love to create a "daemon" which in specified time intervals will move-transfer any zip files uploaded by the users from a.example.com to b.example.com
From the info i gathered so far,
The daemon will be an .ashx generic handler. The daemon will be triggered at the specified time intervals via a plesk cron job The daemon (thanks to SLaks) will consist of two FtpWebRequest's (One for reading and one for writing).
So the question is how could i implement step 3?
Do i have to read into to a memory() array the whole file and try to write that in b.example.com ? How could i write the info i read to b.example.com? Could i perform reading and writing of the file at the same time?
No i am not asking for the full code, i just can figure out, how could i perform reading and writing on the fly, without user interaction.
I mean i could download the file locally from a.example.com and upload it at b.example.com but that is not the point.
I basically want to transfer a file from the client to the file storage server without actual login to the server so that the client cannot access the storage location on the server directly. I can do this only if i manually login to the storage server through windows login. I dont want to do that. This is a Web-Based Application.

Are Microsoft “Express” editions free to develop on? s there software available that allows a developer to write .NET applications with SQL Server for free, meaning without buying Visual Studio and SQL Server.s long as you buy Windows web hosting (w/ support for .NET and SQL Server), is there software tools you can use to develop for free (Visual Web Developer? SQL Express?)
