IIS RewriteMap Rule causes 500 error

Question

I am totally new to IIS servers and need to implement some rewrites. The following rule in my RewriteMaps file causes a 500 error:

<add key="/contenttemplates/news.aspx?id=8589976277&LangType=3081&CurrencyType=156" value="/" />

While this one works fine:

<add key="/offset-air.php" value="/" />

I can only assume the query string has something to do with the issue, but I struggle to find a reason as to why this URL would be an issue. Initial google attempts have come up empty.

I would be very grateful if someone could point me in the right direction.

Many Regards!

Answer 1

If your rewrite maps are causing you issues, you should consider encoding your urls correctly.

An & in the URL (in either the key or the value) should be replaced with an &.

 <add key="/contenttemplates/news.aspx?id=8589976277&LangType=3081&CurrencyType=156" value="/" />

would then become:

 <add key="/contenttemplates/news.aspx?id=8589976277&amp;LangType=3081&amp;CurrencyType=156" value="/" />
