IE6 ajax oddity

[BruceMacKay]

Folks,

I have a small blog application at http://www.thomasbaine.com/thetuis.asp

The application works fine in IE7 and FF on both the production
server (above) and my local development machine.

IE6 works fine on my local machine, but fails on the production server.

By fail, I mean that ajax calls to the server are not returned.  For
example, I can post a comment - and it will be stored in the database
- but the return ajax stream of data to update the page does not
arrive.  Similarly, click on the "Recent" links to retrieve previous
items of the blog do not "work" - the server receives the instruction
and does the processing, but the return ajax stream doesn't seem to arrive.

Any ideas?

Thanks/Bruce

Hi Bruce,

Someone with more experience on this than me can hopefully jump in  
here, but I noticed your server's response headers for those "Recent"  
link AJAX requests contained:

Content-Type application/json

I see that you are specifying that as the "dataType" option on  
your .ajax() calls, so that's all good.

But I remember a comment that someone entered on J�rn's blog  
regarding the validation plugin (which often uses JSON data) about  
the page's "Content-Type" meta tag being UTF-8, such as:

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

Apparently under certain conditions, this content-type can cause IE 6  
to have fits with JSON (and perhaps other dataTypes) Ajax responses.  
I'm not sure if somehow making sure the responses are encoded in  
UTF-8 would help (to be honest, I'm not exactly sure if that even  
makes sense?). But apparently, changing your page's "content-type"  
meta tag to:

<meta http-equiv="Content-Type" content="text/html;  
charset=ISO-8859-1" />

...will often help make IE 6 behave like a good little browser.

Sorry if that's not any help. But hopefully this could fix the  
problem you're seeing.

Good Luck!

I don't have IE 6 right now, so i won't be able to test the page, but, typically these types of behavior is seen when there is some script error in IE. check to see if there is some error in the javascript end.

Theo, your link fixed my problem as well.

It seems that IE 6 sometimes wants a few carriage returns in served
JSON content when it is parsed.

Thanks!
