How can I get request parameter value if value is hash symbol (#)

I have the following request url:

localhost:8080/MyApp/browse/alphabetical/result?startsWith=#&page=1&size=10&sort=title&order=asc

Notice the request parameter "startsWith=#".

I am unable to get "#" as the value of the 'startsWith' request parameter. Instead, I get an empty string ("") as the value of the 'startsWith' request parameter. Is there any possible way to get "#" as the value of the request parameter?

THIS DOES NOT WORK: ${param.startsWith eq '#'}

THIS WORKS: ${param.startsWith eq ''}

If there is no way to handle this, I will have to resort to using startsWith=0 ... startsWith=9 instead of startsWith=#, which I really don't want

You cannot send a # with query string like that. It won't be a part of query string.

Quoting RFC - Section 3.4:

The query component is indicated by the first question mark ("?") character and terminated by a number sign ("#") character or by the end of the URI.

You need to encode the parameters in query string, before sending request. For e.g., In a JSP page, you can use <c:url> JSTL tag:

<c:url value="/MyApp/browse/alphabetical/result" var="url">
  <c:param name="startsWith" value="#" />
  <!-- Rest of the parameters -->
</c:url>
