Web Forms :: Server.Transfer And Response.redirect In Multi User Environment ?
Jan 27, 2011
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 ?
rl711 You have to use target attribute in form tag: <form runat=server target=_blank> // new window or <form runat=server target=_top> // above all frames or <form runat=server target=_parent> //parent frame or <form runat=server target=someframe> // a frame by name
This can only work if the Server.Transfer is invoked from within the form such as a button click.
If your Server.Transfer method is in the Page_load event (which isn't a form event), how do you set a target window to Server.Transfer?
This is the very favourate question available on every interview questions site. I have searched for it. But didnt get the satisfactory practical difference between these two. show me the difference between this two through a working sample demo.
I am working with asp.net 2.0 and sql server 2005. so trying to describe it below:
THE SITUATION
I have a few tables to hold data for billing information. The first table has each dedicated to each location, and a serial number that can be incremented. The concept is to update this data based on location, every time there is a new bill, so may be location A has serial 25 since it is doing well but location B has serial 5.
THE PROBLEM
SO based on this requirement I need to update a table to get the latest serial for a particular location and then use that serial for other tables which will be holding the billing details. The second part is as regular as it can be, but generating a new number, and getting this value is my problem. Since this will be multi user system, so I want some robust solution. I do not know whether I can use a identity field for this purpose or not.
We are looking to integrate Memcached into our infrastructure, but have a security concern before we do. We run several platforms including ASP.NET and ColdFusion and have many app developers working many little applications across the different platforms. The concern is this: App A places item "dog" into cache.
App B reads item "dog" (or worse: App B updates item "dog")
After this happens, App A either retrieves bad information, or has already had its information viewed, aka "stolen". What we would like to do is make it so that each app can only interact with its own sandbox, and may not interfere with or read other application's data.
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]
Try client.Send(msg) Global_asax.myLogger.Log(BitFactory.Logging.LogSeverity.Status, (-- Status --> form sent email to " + msg.To.ToString)) btnSendmail.Enabled =" "False" Response.Redirect("http://www.google.com/")
i am submiting a form on the button click and redirectiing to a site. But it is not working.
Our current application is working fine but when you try to misbehave like we found out that When login with same user in multiple tab with different organization(there is a organization dropdown in the master page which sets the cookie whenever it is changed.) in tab one it is org 1 and tab 2 it is org2 , cookie has the later org 2 in it but when we go back in tab1(which had org1) and save the record org 2 will be saved with the record So can some one share some sort of a checklist with us which address these types of problem.
I am using a custom event in third party library for my asp.net project. When the event happens, I need to redirect to another page. Problem is that since it is custom event, Server.Transfer or Response.Redirect can't be used (I tried but got "response is not available in this context"). So I think best way would be to trigger post back in the event and redirect in page_load event on appropriate conditions. Is this right approach or is there any better idea? And, how can I trigger postback?
Followed the code sample of Chapter 10 (Logging in) of the Book, Microsoft ASP.NET 2.0, I created an ASP.NET 3.5 website with Forms Authentication. The sample code used Website Administration Tool (WAT) to manage the users, roles, and authorization.When running in the ASP.NET Development server environment, I can first login, then click to open the links for each for the 3 roles.
However when running the sample code in the IIS server environment, I can login but can not open the links for the role subfolders.Clicking each link popped up an error message for opening a login.aspx from the specific subfolder. I don't have a Login.aspx file in each subfolder.The 3 role subfolders were configured as the virtual folders in the IIS Server. Why the sample code worked fine inASP.NET Development server environment, but got an error message from theIIS Server environment? Why an authenticated user can not open the subfolder homepage?
we are running into an issue with our ASP server. If you try to access a password protected page it does a security check and redirects you if you are not logged in, retaining the URL (ie. Members/MemberLogin.aspx?doc=/PodCast/Default.aspx) The vb script places the "/PodCast/Default.aspx" in a variable and holds it until the login process is complete. Once the user types in their username and password it is suppose to do a Response.Redirect(strRedirectURL) and go to the "/PodCast/Default.aspx" but instead it goes to the default.aspx page for logging in successfully.
The kicker is, I know the code is 100% correct becuase it was working on our previous server, but when we pushed all the data onto this server, everything works BUT that piece.
if ((Request.QueryString["UbytovaniePrispevokID"].ToString()) == "")[code]......
What i want to do is.. I have one main page with new posts Each subject of the new post is the link to Another page where is Specific post and coments and user can leave a coment.
What I want is when the Request.QueryString["UbytovaniePrispevokID"].ToString()) == "" or null I want to redirect to error page ...
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 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 want to redirect to "~/City/Göteborg", but if I just write Response.Redirect("~/City/Göteborg"); I will end up with an ugly URL in the address-bar like this: http://www.mysite.com/City/G%c3%b6teborg..
So my question is how to redirect to obtain a clean url like http://www.mysite.com/City/Göteborg?
We have a simple ASP.NET app that uses the ASP.NET SqlMembershipProvider and all is great.
We want to create a second app on the same server, also use the SqlMembershipProvider, but a different "applicationName" so that the user accounts between the two apps are kept separate.
It looks like this would be possible by making the two different app domains (ie they each have their own web.config), but I'm hoping to just put them in different directories so I don't have 3 web.configs (one for each app, and the main one) that all have to be kept synchronized. So what I'm after is:
/web.config /APP1 (uses membership provider in /web.config, with userlist A) /APP2 (uses membership provider in /web.config, with userlist B)
It looks simple to define multiple membership providers that use a different 'applicationName' value.
But how do you tell the system.web.authentication node which membership provider to use?
