uppercase lowercase bug..web dev

Hi I am facing a weird bug, I am writing a tag like

<div id="thecontent" dojoType="dojox.layout.ContentPane"></div>

Please see the "T" in dojoType it is in uppercase.Now I go and see my page not rendered properly, so I view source and I find that the source is correctly shown, but开发者_高级运维 when I check firebug , I get this:-

<div id="thecontent" dojotype="dojox.layout.ContentPane"></div>

Please notice that t in dojotype here it is small. I went ahead and changed the entire dojotype to UpperCase , but it is still rendered as lower case.

I even checked in other browsers, and it is the same. Has someone faced anything like this. If so please tell me how to handle this.

I am tired of this.

{update:-Please find attached a screenshot of wireshark when I do a refresh.. unable to understand a thing}

Using a packet sniffer such as Wireshark will tell you if it's a server-side or client-side problem.
