Internet Explorer has some interesting foibles. And by interesting, I mean annoying.

For instance, if I’ve visited a page on my site, such as:

http://schinckel.blogsome.com/wp-admin/

Internet Explorer seems to remember it as

http://schinckel.blogsome.com/wp-admin

Notice that the trailing slash is missing. Blogsome will report that “Page Does Not Exist”, or if it looks like a Post page, “No posts made”.

With access to the HTTP server, this would be easy to fix (just create a rule in the relevant place that allows for URLs of this form), but on Blogsome this is a bit harder. You need to be able to check the last character of the URL string, and if it isn’t a /, append one. This should work fairly well in all cases, since every reader visible URL ends in a /.

So how to do this? Getting the URL is easy: {$smarty.server.REQUEST_URI}. However, getting the last character is a bit more difficult. Or so it appears. But Smarty allows for accessing strings as an array, so {$smarty.server.REQUEST_URI[0]} will get the first character. To get the last is a therefore possible. {$smarty.server.REQUEST_URI[-1]} fails, so I’ll need to get the length of the string.

{$smarty.server.REQUEST_URI[$smarty.server.REQUEST_URI|count_characters ]}

also fails, but

{$smarty.server.REQUEST_URI[smarty.server.REQUEST_URI|count_characters ]}

works.

Now, we just need to test if this value is “/”, and if it isn’t, then reload the page with that added.

Which I can’t seem to figure out how to do with Smarty…

Of course, doing the same with JavaScript is a piece of cake:

if (document.URL[document.URL.length-1] != “/”)
    document.location = document.URL + ‘/’
