A small HTML or possibly java problem.

A small but annoying problem.

I have recently uploaded my website to a free hosting site at t35.com. Everything looks fine when it is viewed remotely via a browser in the usual way - but one annoying problem. When I type the full domain name in my browser to view the site remotely the main index.htm page loads but the images sometimes fail to appear . If I use the full path to the index.htm file the page loads fine, including the images with no problems.

I have tried using full web paths to all the images, checked capitalization within the HTML document and I have also tried renaming the index.htm to index.html - all to no avail. I understand the server is using an apache web server and it should be looking to default to index.htm anyway. The page contains some java rollover features and I am wondering if this is the cause of the error or could it be a server side problem?

There is probably a small fix for this but I cannot find it. Any advice would help me enormously

Domain name - intermittent fault
default index.htm here - working

Thanks.

Seems to work fine from my browser (IE6).

I clicked on both links and neither gave me a problem with the images.

Edit: I also hit refresh a couple of times to see if it would change anything, and that didn't give me any problems either.

Hate to break this to ya... but neither work for me... both show up with an image of "Goo" taken from the Google web site, and nothing else... That supposed to happen?

Yeah thats happening all the time. I'm assuming the google logo is loaded if there is a problem loading the correct image. Maybe I'm wrong.

Both links worked fine for me (IE6 also). I clicked on each of the links within the main page, and they seemed to work correctly also.

I checked out the source of the index.htm, and it doesn't look like the images you're trying to load exist. I tried copyinga few of the locations of the image files and queried them and they don't seem to exist. Have you made web pages before? What did you use to make it? It's possible that when you uploaded the page, the images weren't uploaded to the proper place... Also, somewhat related, are you sure that your web site host allows Java Script? Did you test it locally before posting it to ensure that, in case it does support Java Script, that you don't have any errors in your Script? Just some suggestions you may want to look into....

Tested about 20 times in IE 6.0 http://vorpel.t35.com/ and http://vorpel.t35.com -- No problems

Tested about 20 times in Netscape 4.72 http://vorpel.t35.com/ worked most of the time-- http://vorpel.t35.com usually caused netscape to crash. But I think that is just because it is netscape.

Looks good btw.

Try using this in your source. It will make sure that the base-path which is used in your code is correct (don't know if it'll work with the javascripts though). It should be located between the <head> tags.

Code:

<BASE href="http://vorpel.t35.com/index.htm">

Well, I don't know if this would cause the problems that you're experiencing, but you don't seem to ever close the tags with a . Since these tags are how you're controlling the mouseovers, they might cause those quirky problems. You just never know how a broswer will handle incorrect tags.

Here's source code from a page I once wrote in case it helps. It seemed to work.

Code:

<script language="JavaScript" type="text/javascript"> function onto_zero() { document.images[0].src='images/HomeOver.gif'; } function offof_zero() { document.images[0].src='images/Home.gif'; } function onto_one() { document.images[1].src='images/InformationOver.gif'; } function offof_one() { document.images[1].src='images/Information.gif'; } function onto_two() { document.images[2].src='images/ResourcesOver.gif'; } function offof_two() { document.images[2].src='images/Resources.gif'; } if (document.images) { pic1= new Image(140,35); pic1.src="images/HomeOver.gif"; pic2= new Image(140,35); pic2.src="images/InformationOver.gif"; pic3= new Image(140,35); pic3.src="images/ResourcesOver.gif"; } </script> ... blah ... blah ... blah ... <a href="index.html" onmouseover="onto_zero()" onmouseout="offof_zero()"> [img]images/Home.gif[/img]</a> <a href="InfoMenu.html" onmouseover="onto_one()" onmouseout="offof_one()"> [img]images/Information.gif[/img]</a> <a href="ResourceMenu.html" onmouseover="onto_two()" onmouseout="offof_two()"> [img]images/Resources.gif[/img]</a>

Good luck.

First Edit: Added Source Code
Second Edit: Removed that crap that was frame specific from the source code.

avdven ==>
The code works fine locally. I don't think it is java problem because it is an intermittent fault and my host does support java script. All the images used were loaded many times to the correct directory of /images. The code was not written using a wysiwyg editor just textpad, I find it easier - and yes I have written web pages before with no problems.

Guus ==>
I tried your suggestion of adding a BASE href reference between the head, tags, same result.

str34m3r ==>
I also tried closing the <a href=""> tags this also caused the same fault.

I am starting to think it is most definately is a hosting problem. I am going to try to host it somewhere else and see if that resolves the issue.

Any more suggestions would be greatly appreciated.

Ok... another update for you. Your problem is definitely with your hosting service. I opened a window with tcpdump running with the command line:

tcpdump -i eth0 -s0 -X 'port 80'

Then I browsed to your page and found this interesting snippet in the tcpdump:

If you pardon the mess, you'll notice that your hosting service doesn't like for people to directly link to images, so if they see an HTTP request that doesn't have a "Referer:" field, they give you a 302 Redirect message which sends you to Google to download part of Google's logo. My guess is that some browsers fill in the "Referer:" field differently than others, thus creating your error that appears differently on different browsers.

In other words: get another server to host your site.

the problem exists because the host does not allow deep linking from outside of the parent domain. the other end of this is that javascript image loaders do not use http_referer headers in some browsers.

sorry str34m3r...i had it up and open for awhile before submitting.

I think I understand this deep linking idea. But what I'm not sure of though is how this is related to _my_ site. All the images were originally situated within the same directory on the same host URL until the problems with image loading started. I then changed the paths of the images to full web URL's. The annoying thing is that it is a very intermittent problem, sometimes working fine and encountering no problems whatsoever.

I would be very grateful if anyone could expand on what deep linking really is and maybe hear what everyone thoughts are on this new web practice.

Thanks again.
