Page_Load function repeating twice not on postback

Hi there,

We're creating an application at the moment which is very close to going live, but we have a strange bug which is really causing hair to be torn out. Basically, this program runs through an initial process where the user moves through the initial stages, and then once information has been collected, the data is passed through to a secondary assembly page.

Once the assembly page has run through the code to assemble the document, it is redirected to a function called displayDocument() which executes specific code based on whether the document is to be assembled as a PDF or an RTF. Now, out of four possible outcomes (based on PDF/RTF and another variable) three of the outcomes work correctly.

However, the fourth one (when we try to write out an RTF) causes the Page_Load event to fire twice - ie it will assemble the document, save it and hit the response.End() line, but after that it will inexplicably return to the top of the page_load function and start over, producing a blank document with no answers.

I'm hugely confused by this as like i say, there are three outcomes which work fine, but this final one causes all the problems - I've attached the code snippet below which shows the code that's causing the problems, but if you need any more let me know. This snippet is at the end of an if statement and after that there is no more code - not sure if thats a problem or not.

Anyway, if anyone has any ideas, they would be gratefully recieved.

Cheers

Andy

                Response.AddHeader("content-length", buffer.Length.ToString());
                Response.BinaryWrite(buffer);
                //File.Delete(outputpath + "\\" + fname);
                Response.End();
            }
