In the course I'm taking they taught me to use Response.Redirect like this:
Response.Redirect(string.Format("name.aspx?sb="+bts+"&del="+delimiter));
Is there a better way to do so?
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 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.
How we transfer my session from http page to https page.

how do I transfer my data to another page.
Have 3 textbox whose value must be transferred..
just a quick question -i cant get my class in App_Code to work in my code behind page for simple .net page, some light what doing wrong?
[Code]....
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.
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
What's wrong with this code?
Source page : Default.aspx
[Code]...
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) ?
i have a problem to transfer data from first page to another page...

View 1 RepliesI am new at this VB/Microsoft Visual Web Developer 2010 Express thing. I am amaze that I even got this far and thatI manages to make this search page work. Below is the code and picture for this search page. It's working. However I want to transfer the result/the gridview onto a second page Result.aspx. But I tries all kind of thing and it just doesn't seem to want to cooperate with me. If anyone can give me some hint/some sample codes on how I might be able to transfer controlfrom one page onto another. I just have to learn it from a class extra credit project. Also in the picture above I am using a direct connection to an Access database not the ObjectDataSource. I was just playing around with it to see which is better. But I ended up going with direct connection to Access database.
