Using Response. Redirect and Response. Write from flat class file Setup: I developed an interface that holds certain functions that are shared between some users in my system. The different users are grouped into classes that implement that interface. Problem: In some instances the implementations of this interface include a mere write to the screen or a redirect.
However, when I attempt to do something like Response. Won't let me use both Response. Redirect in same function? Below is my code:Response. Redirect "forms. When that function is called it directly redirects me to forms. How can I fix that so that it opens the new window and then redirects the user to a different page in the old window. Using Visual Studio Language: C Write gives a formated output OR Response.

Write Hey guys I am using a FileUpload control and trying to display the pdf file. I can't get it to show the pdf file when I use Response. But if I save the file to a directory and use WriteFile instead I can get it to work. I tried eliminating the repeated Write calls and simply using a temporary StringBuilder.
I varied the capacity of the StringBuilder, but this next code worked well. Faster version. Here I made a couple changes.
I split up the Response. Write calls to send one argument at a time and not concatenate anything beforehand. This was a substantial speedup. Next we see a further improvement.
This changes the output but in this case it didn't matter. I ran the above code fragments 20, times each with a dictionary of key-value pairs.
The output file was 4 KB and I used Response. Clear to erase the buffer each time. The figures from the experiment are available here. Improvement 2.

Properties are slower than local instances. This security risk is referred to as a cross-site scripting attack. You should always validate data that is received from a client when it will be transmitted from your site to client browsers.
Moreover, whenever you write out as HTML any data that was received as input, you should encode it using a technique such as HtmlEncode or UrlEncode to prevent malicious script from executing.

When you encode or filter data, you must specify a character set for your Web pages so that your filter can identify and remove any byte sequences that do not belong to that set such as nonalphanumeric sequences and could potentially have malicious script embedded in them.
