My rewrite rule give me a 500. What is wrong?

Question

When I add a new rule to Web.config I get a HTTP 500 error. I'm on Azure.

The following give an error message:

<rule name="Rewrite ticket and segment" stopProcessing="true">
    <match url="^([A-Z]{3}[0-9]{4}[A-Z]{1}[0-9]{4})\/([0-9]{1,5})\/?" />
    <action type="Rewrite" url="/api/getTicket.php?ticketId={R:1}&segment={R:2}" />
</rule>

but this one it working :

<rule name="Rewrite ticket" stopProcessing="true">
    <match url="^([A-Z]{3}[0-9]{4}[A-Z]{1}[0-9]{4})\/?" />
    <action type="Rewrite" url="/api/getTicket.php?ticketId={R:1}" />
</rule>

Answer 1

The Reason is, you have invalid XML . Since web.config is XML based & is not that what you think.

Change the & to & and it will work.

<rule name="Rewrite ticket and segment" stopProcessing="true">
    <match url="^([A-Z]{3}[0-9]{4}[A-Z]{1}[0-9]{4})\/([0-9]{1,5})\/?" />
    <action type="Rewrite" url="/api/getTicket.php?ticketId={R:1}&amp;segment={R:2}" />
</rule>
