hi all,

while uploading javascript for the google analytic code on my live site i am getting below error.

Server Error in '/' Application.
A potentially dangerous Request.Form value was detected from the client ((ctl00$ContentPlaceHolder1$txtanalyaticcode=")


<script type=”text/j...").
Description: Request Validation has detected a potentially dangerous client input value, and processing of the request has been aborted. This value may indicate an attempt to compromise the security of your application, such as a cross-site scripting attack. To allow pages to override application request validation settings, set the requestValidationMode attribute in the httpRuntime configuration section to requestValidationMode="2.0". Example: <httpRuntime requestValidationMode="2.0" />. After setting this value, you can then disable request validation by setting validateRequest="false" in the Page directive or in the <pages> configuration section. However, it is strongly recommended that your application explicitly check all inputs in this case. For more information, see http://go.microsoft.com/fwlink/?LinkId=153133.

Exception Details: System.Web.HttpRequestValidationException: A potentially dangerous Request.Form value was detected from the client (ctl00$ContentPlaceHolder1$txtanalyaticcode="

This type of error occur when you try to post some Html code or other scripting code in the field which is not assigned to fetch such values... Plz check the nature of Input and proceed..

Hi Vishal,

Thanks for the reply. i have just found my solution.your are also right it was problem due to "<" and <script> tag.so i statically write <script> tag where i want it and then get dynamically js code between <script> tag.it works fine.

Thanks again,
KK

This error is generated by ASP.NET to avoid cross site scripting issues.
The solution is to set
<pages validateRequest="false" />
If your .NET runtime is 4.0 or above:
add the following to web.config:
<httpRuntime requestValidationMode="2.0"/>
