    <p>I'm trying to echo out a url in my classic ASP (JavaScript) pages. I have a little function to append a query string to the URL and echo it. My problem is that my string is being modified before being output; the protocol is changed to match the current protocol (http / https) and the subdomain is also changed (www or nothing). I don't want this to happen.</p> <p>Here's my function that I'm using to append the query string:</p> <pre><code>function writeUrl(langcode, url) { if(url.indexOf('?')==-1) { url = url + '?lang=' + langcode; } else { url = url + '&amp;amp;lang=' + langcode; } Response.Write(url); } </code></pre> <p>Pretty simple, no? This function is included in the top of the page in question like this:</p> <pre><code>&lt;!-- #include virtual="/inc_url.asp" --&gt; </code></pre> <p>Lastly, in the page itself, I call the function. The 'lang' attribute is a 2-letter string.</p> <pre><code>&lt;% writeUrl(lang, 'http://www.example.com/somepage'); %&gt; </code></pre> <p>On visiting <a href="http://example.com/somepage?lang=fr" rel="nofollow">http://example.com/somepage?lang=fr</a> I would have expected the above code to echo this:</p> <pre><code>http://www.example.com/somepage?lang=fr </code></pre> <p>However, I get any of the four following values, each one matching up with the URL I'm visiting:</p> <pre><code>Http://example.com/somepage?lang=fr https://example.com/somepage?lang=fr http://www.example.com/somepage?lang=fr https://www.example.com/somepage?lang=fr </code></pre> <p>Can anyone point out somehing I'm missing? I'd like the URL to be output without that kind of modification: I want to use it for rel=canonical.</p> <p>And no, re-writing it in .net is not a possibility.</p> <hr> <p>New information - Even the URL when hard-coded into the html, even in a comment is changed. So, if I put <code>&lt;!-- http ://www.example.com/ --&gt;</code> into the html, then when I access it from <a href="https://example.com" rel="nofollow">https://example.com</a>, it has been re-written as <code>&lt;!-- https ://example.com --&gt;</code>. This seem to confirm it's something down-stream. Any more ideas? (spaces added above so I don't exceed max number of hyperlinks).</p>

    1. CODo you have a public-facing page where we can see this?

    2. COI'm under an NDA for this site, unfortunately. However, it's exactly as I mention above - if I go to https://example.com/somepage?lang=fr then that is the URL that's echoed, rather than the one I've specified in the code.

    3. COYou did give me an idea, though. If the URL does not relate to the current URL (if it's for another domain), then it behaves as expected - as I want it to, without modifying the protocol or subdomain. So it only happens when the URL can access the current page. Unfortunately, that doesn't help me...

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
