as u know, you can call Server.Transfer() or place some values in Session["objName"]=value; inside your page. but i'm writing a class which has not page, so it does not have any Server or Session object.
how can call this objects or methods outside of the page (within my class) ?
Sometimes when transferring to a different page, I have to use response.redirect instead of server.transfer, and when I do, the name of the page always shows up in the url such as [URL]
I use server.transfer when I can, but unfortunately I haven't found a way to use it unless the transferred page refers back to the parent when leaving.
How can I mask what page is being viewed after doing a response.redirect to another page.
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.
To get the url of the current page, I usually do something like this:string path = Request.Path;If I do this after a Server.Transfer then I get the path of the page where the transfer was done. How can I get it for the current page?For example:
On Page1.aspx I do Server.Transfer ("Page2.aspx")
On Page2.aspx Request.Path returns /Page1.aspx and not /Page2.aspx
i have two servers s1 and s2
In s1 we hav an aspx page called test1.aspx
In s2 we hav an aspx page called test2.aspx
In test1.aspx i have a textbox and a button. I enter data in textbox and click the biutton.
Now the data that has been entered should be shown in a label in test2.aspx
test1.aspx and test2.aspx are in two servers...so how to do it ...
I have a very simple application. You have a master page. Within the CS of the master page you do a Server.Transfer to another page that inherites the master page. As a result you get an infinite loop. The problem is that I can't check with if statements to prevent the loop.
View 2 RepliesI open a pop up page(child page) by using jquery(jquery.colorbox.js) in asp.net application. now when I click on search button I want to close the pop up page(child page) and refresh the UpdatePanel1 by using search parameters. for above I need to execute server side function in parent page. code to close pop up:
child.aspx:
<script>
function closePopup() {
[Code]....
protected void btnCancel_Click(object sender, EventArgs e)
{
Server.Transfer("Fix_Details.aspx");
}
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.
I need to pass api key in custom http header ('X-ApiKey') and pass to another page. The second page will read that api key and do further processing. If api key is not passed in, it will redirect to error page.
I tried this way, but it didn't work.
In First.aspx page
Response.AppedHeader("X-ApiKey", "xxxxxxxxxx");
Response.Redirect("Second.aspx");
In Second.aspx page
string apikey = Request.Headers.Get("X-apiKey");
but X-apiKey is not passed in in second.aspx http header and ended up redirecting to error page.
I have a parent page with two data controls. I want to be able to open a child window, do something on it, and when it closes I want to rebind only one of the two data controls on the parent page. I have the control I want to update within an UpdatePanel so would like to call rebind it and call UpdatePanel.Update().

I'm trying to post a value to an external site and have managed to piece it together using HttpWebRequest. My problem is that this behaves like a server.transfer. ie it maintains the url. As a result the page I'm posting to doesn't link to any of it's images or stylesheet. Can anyone give me a simple way to do an old style post to an external site?

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?
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 ?
View 11 RepliesI 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.

View 1 RepliesI 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 remove a temp file from the server after the user close the page (I assumed I don't have this callback on the server by default),
I tried to call a server side method using (ICallbackEventHandler implementation) when the user close the page, but the problem is that the server side method doesn't fire in this case (closing the page), it only response if the page still opened. and I don't prefer to stop closing the page until the server response and send its call back to close the page manually.
