Random Development/Computer Tidbits

So here are some interesting things that were learned today:

• When trying to check the HTTP_REFERER using a .htaccess file links generated by JavaScript don’t set the referrer.  However, this is apparently only an issue in IE (we only tested IE and Firefox)
• IE doesn’t like some JavaScript parameter names when using jQuery – but they work perfectly fine in Firefox
• When PCs don’t have enough memory to perform a process in a software program, they apparently also don’t have enough juice to close the same said program – Hello Task Manager!! (or hello Mac :/)
• IIS can act like Apache mod_rewrite, just make sure you don’t use the Lite version if running multiple website.

Internet Explorer with CSS :hover

I discovered an interesting thing about Internet Explorer today while trying to change the border color of an image on mouseover.  IE only recognizes :hover on links, or <a> tags. So, something like this, which works perfectly fine in other browsers, will not work in IE:

a img {
border:1px solid #581C00;
}

a img:hover {
border:1px solid #ffffff;
}

To make this work in IE it needs to be done as follows with the :hover applied to the a tag:

a img {
border:1px solid #581C00;
}

a:hover img {
border:1px solid #ffffff;
}

SWFObject/Internet Explorer abort message and fixes

Another issue that we ran into recently when launching a site that used Flash was an error message in Internet Explorer 7 on a PC (Vista for me).  When trying to access the home page, the following error was displayed: “Internet Explorer cannot open the Internet site . . . Operation aborted” and killed the page rendering and showing a page cannot be displayed message. This, of course, made the homepage inaccessible.

I ran into an issue today sending emails from a CMS system that was running on a WAMP installation due to the client’s request.  We were using the default PHP mail() function to send emails from the form and the emails were not sending.
