301 URL encoding on IIS

Question

So I'm trying to set up 301 redirects on my site and all of new pages use JQUERY tabs, since JQUERY tabs use specific ids to open a new tab I tried setting up my 301's like /folder/file.html#tabId. So my 301's will actually look something like this:

• products/productname-overview.html -> /product/productname.html#overview
• products/productname-features.html -> /product/productname.html#features
• products/productname-specs.html -> /product/productname.html#specs

(So all my content will be in a single page now)

I'm currently working on IIS 8 and I understand there are some rules that encode several characters on my 301's, so I also tried encoding my new urls but it seems that when it detects the %, ISS tells me is invalid.

• products/productname-overview.html -> /product/productname.html%23overview

Error log: A potentially dangerous Request.Path value was detected from the client (%).

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Web.HttpException: A potentially dangerous Request.Path value was detected from the client (%).

Is there a way to make a rule for only the "#" character? Any suggestions on how to fix this issue? Thanks!

Instead of redirecting to a fragment, you could pass the value of the fragment in a query string and retrieve it with js. Your redirect entry would look like:

products/productname-overview.html -> /product/productname.html?fragment=overview
