C# - Server To Server File Transfer Without Any User Interaction?
Feb 16, 2011
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 want to transfer a file from client machine to Web server. I need to allow the users to select a file on their machine and allow them to transfer the file to the web server? Also How does a file control work.
<INPUT id="File1" type="file" runat="server">
How to allow the users to transfer files to web servers from their local machine?
I have to choose between Server.transfer and Response.redirect for an Intranet application for navigation. I have chosen Server.Transfer as of now because it avoid extra round trip to server and which will help when so many users will be accessing the application. (I believe this is the main difference between reponse.redirect and server.transfer). But the problem is now that URL won't change on Server.Transfer(I don't want to implement Http headerS, as I am afraid it will take time to implement that).on redirection, I want to do something like taking benefit of server.redirect(in avoiding server processing, which happens in response.redirect) and changing the URL(as it happens in reponse.redirect).Can anyone please suggest a quick solution to it or may be help me Telling How many users can reponse.redirect can support ?
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.
how to transfer my data from devlopment server to production server ,i have already records exist in my database if i go for script then how can i transfor record in script i can transfor only table ,procedure and views.I am using SqlServer 2005.
I have a large dataset (35,000+ rows) that I need to export to excel and then let the user download. I have done this the conventional way (with a gridview), but the data has grown, causing a OutOfMemoryException on the web server.
So I thought, would it not be better if I can export the data into excel on the sql server, and then transfer this data to the web server.
Note that this is not a one-off job. This will be ran regularly (twice a month), but the user. Hence I need something that the user can initiate.
We have developed one Web Application which is running in only one server. Now client needs our application be in two servers. So if one of the servers down then another server should be working. We are using sessions in our application. Now the problem is how to transfer the session data from one server to another??
This is kind of cross-post; however, can a custom http handler be automated to run either using a timer or a filesystemwatcher to post an xml document to another server (with no human interaction)?
I have a requirement where I have to transfer a user from Web Site 1 on Server A to web Site 2 on Server B.
On Web Site 1, I have to provide controls to enter user id and password and which have to be validated on Web Site 2 on server B, after validating them I have to redirect the user to Web site 2.
what is best way fo doing it. code examples are greatly appreciated.
Note: On Web Site 2, user login functionality is already existing and it is provided by ASP.Net login control, am not sure how to handle the user login process from two different places.
or is it the best way to move Web Site 2 from Server B to Server A so that, the same login controls will be shown using Iframe on Web Site A.
What is Web services? What is Web services? How can I Transfer the data from server to client and client to server using XML. Need one simple Example program(C# web Application) ...
I need to upload a file (xml, pdf, etc) from the user's PC, but I need to write it directly to a file server. I cannot use FileUpload because there is no way to direct its initial upload to anything but the web server. So, how do I use the HTML INPUT to upload the file from the user's PC directly to a file server located at a different URL than the web server the web page is being hosted on?
If I need to redirect a user from one page to another, should I use redirect or go with server.transfer? I'm assuming redirect. The idea is to give the users one specific URL and then have that URL redirect to the most current iteration of the page. For example, the user may have [URL] as the URL but the actual page served to them would be [URL]
Server.Transfer is not redirecting the page. It stays on the page that the button was clicked on. The message is "Error on Page."I tried Response.Redirect and that didn't work either.
Basically I have a page where a user can select up to 3 vehicles by make and model. I have 3 divs on the page that is generated with a basic foreach loop. When the user selects a make and model from respective dropdown lists I am firing a javascript function that returns a JSonResult that loads a dynamic partial view into a seperate div. This partial view displays a div with a grid whereby the user can select one of n-number of services using a checkbox.Next what I would like to do is if the user selects a servce for the one of the vehicle selections, I would like to add this selection to a list of "ServiceSelection" that is part of my viewmodel. Ultimately the user would click a button that would redirect to the next step in the process and pass the entire updated viewmodel to this new page.
A first chance exception of type 'System.Threading.ThreadAbortException' occurred in mscorlib.dll An exception of type 'System.Threading.ThreadAbortException' occurred in mscorlib.dll but was not handled in user code
After banging my head because i could find where the exception came for and global.asax didn't get hit i found that it's from server.transfer and is a known bug. The alternative i read about is server.execute.However if i do this then the next page fires multiple javascript exceptions and a gridview i have is breaking of and the rows appear half at the left page corner and half inside the gridview!!
For now i just put a try catch on the server.transfer although the exception will not affect the application even if i don't use try catch. I also see that the exception is happening again even if i put try catch but with different dll: A first chance exception of type 'System.Threading.ThreadAbortException' occurred in App_Web_benglxq1.dll An exception of type 'System.Threading.ThreadAbortException' occurred in App_Web_benglxq1.dll but was not handled in user code Now what on earth is benglxq1.dll i don't know. What i know is that i'm leaving an exception to run and i don't like that. This is the js error when i use server.transfer btw: Microsoft JScript runtime error: Sys.ArgumentTypeException: Object of type 'Sys._Application' cannot be converted to type 'Sys._Application'.
I have one website running on one server and another web application running on another server. My web application asks for username/password to login into the system. I need to put a username/password field on my website so that user can directly login from website. how to transfer these username/password values to the web application running on another server?
I have a custom error handler in the global.asax's Application_Error method, when an error occurs I use the following code to transfer user to the error page:Server.Transfer("/Error/");
However without specifying the actual page name the code above breaks with "Error executing child request for /Error/" exception.So if I use Server.Transfer("/Error/Default.aspx") it works fine with no problems.Also using Response.Redirect("/Error/") works fine too, however we want to keep using Server.Transfer to retain URL displayed in the address bar when the error page is displayed so users can simply refresh the page to retry accessing the original offending URL.Would be grateful if anyone can comment on how to get the Server.Transfer method working without specifying the actual aspx page name.
Currently we are using query-string extensively in our asp.net application. Few days back we were working on enhancing the website. In this we first of all decided not to show the complete url of the webpage on the address bar for this i asked this question regarding it on SO
The best way we got was to use server.transfer(). But now it seems that the query-string does not work with it! Is there a way around this so we may use query-strings and do not display the url of the webpage on the address bar.
If I use Server.Transfer(www.example.com/test/abc.aspx); It is giving and error and saying to give a virtual path. But In DotNetNuke applications they do not have virual paths. So how can I use this feature and i there any alternation for the same thing?
