The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Problem with file download/Response.AddHeader in IE

Asked by hansoninfosys in Active Server Pages (ASP), Web Servers

Tags: ,

I have the following statement in my ASP page:

<a href="DownloadFile.asp?File=<%= Server.URLEncode(myFile.Name) %>"><% Response.Write myFile.Name %></a>

On clicking the link, the code on DownloadFile.asp (see below) uses a request.querystring to retrieve the name of the file. When I click on the link in Firefox, the Save As/Open dialog box opens with the correct filename and if I click Save, it saves the file correctly. eg: myfile08.txt

But when I click on one of the link in IE, it opens the Save As/Open dialog box but asks if I want to Save/Download the file "DownloadFile_asp?File=myfile08_txt"

I am baffled. I know the correct filename is getting passed as indicated by my Response.Write strClientFileName statement at the beginning of the DownloadFile.asp page.

Also, the inline option works perfectly:
   
    Call Response.AddHeader("Content-Disposition", "inline; filename=" & strClientFileName)

but
   
    Call Response.AddHeader("Content-Disposition", "attachment; filename=" & strClientFileName)

only works in Firefox. IE can't seem to figure out what to do with it. Do I have to set up the MIME type in IIS? Why does it work in Firefox then?Start Free Trial
