Caching html pages - no thanks - but how?

Hi.

This issue has bothered me for some time now.

I have quite a normal website, with different html files. If I make changes to a file, I can (sometimes!) see the changes when I hit f5. But if the file is fully replaced (same name and extension though), my browser shows the previous cached page.
So I have to manually right click in the frame, and reload it to see the new version of the page.

After many times googling to address this issue, Ive come up with these meta tages in top of each page:

XML

<META HTTP-EQUIV="CACHE-CONTROL" CONTENT="NO-CACHE">
<META HTTP-EQUIV="Expires" CONTENT="-1">
<meta http-equiv='pragma' content='no-cache'>

But little does it help.
The problem is still there. Why? And how to solve it?

I´ve inspected of other sites that updates several times a day. They have have no special meta tags or alike in their html pages. And it´s of course not nescasary to update the page manually.
Is it a server side setting or what figures?

Thanks alot for your time Smile | :)

This is not a serverside issue, cache control is arranged by the client. If the client suspects the content to be out of date the browser will sent a head request. The server then replies with status 200 if there is a new version.

To disable caching on the browser you can set the following 2 headers:

<br />
Cache-Control: no-cache, must-revalidate<br />
Expires: Sat, 26 Jul 1997 05:00:00 GMT<br />

This should disable browser cache.

json Question

I've written my first jQuery ajax function. It passes a date from the browser to a webmethod in my code-behind. From there the date is verified using a regular expression to make sure someone isn't trying to send something else back. Now, when I tested out this function before with a standard postback, it worked fine. Now, since I'm using ajax I'm getting the message back that my date is invalid, even though I can return it to the screen and it looks just fine.

My question is, how is the string formatted when it is sent from the browser to the code behind using ajax/json? Do I need to parse the date in my code behind?

You need to explain what framework you're using. In MVC, you can create a function that takes a DateTime of the same name, and the framework just magically parses it for you.

looking for an automated form submission program

Need to load a lot of product data to a site that does not accept data feeds. I could manually enter each of my products in a form, submit and continue to product #2, enter form , submit etc... But I'd prefer to find an automated solution...if anyone knows SAP, you do the same thing essentially using something called a BDC program: BATCH DATA CONTROL.

Surely there is something out there to do this. Or an example using perl::LWP e.g.?

any help would be greatly appreciated.

Hi everyone,

I have problem with links on my site (http://troszczynka.pl). I would like to place them permanently on the top of the notebook (just like in the project: http://troszczynka.pl/home.png) and make an animation of rolling out link with jQuery with mouse hover event.

I can manage jQuery by myself but I can't place them exactly on the top of the notebook. I tried to do it but on different screens all the links move into the different places.

HTML and CSS standards compliancy test ?

[edited for clarity on July 7]

Let's say I have a web-site someone did, possibly an "amateur," or someone who clearly doesn't grasp what "standards compliant" is, and has created the web-site equivalent of BASIC "spaghetti code."

My goals here are:

1. Make the code standards compliant: but, not to alter the functioning of the site at all.

2. Cross-browser and cross-browser-version display issues: deal with issues of cross-browser display validation, and, possibly, make it display properly on the usual gamut of browsers/versions.

I realize these are two different issues, even though I think it's possible that having fully standards compliant HTML and CSS might make some impact on cross-browser display issues.

Are you using any tools now, paid, free, or, on-line, to help you analyze these issues in, or QA of, revising a site's HTML and CSS ?

thanks, Bill

Thanks, Graham,I am aware of that tool, and consider it a definite must-use in the diagnostic phase.

For handling cross-browser compatibility, I am considering the whole gamut of external JS libraries, including (for HTML5) BoilerPlate[^]. For mobile-device display issues I'm finding this article helpful:[^].

And then, there's, of course, Modernizr[^].

But, I am not optimistic that given web-site "X" written by someone's uncle, with the crudest possible HTMl/CSS, that will ever be able to be automatically brought up to standards, without hand-tuning by someone who understands standards compliancy, and the inevitable cross-browser testing, and cross-browser-version testing.

However, there are lots of tools for cross-browser testing I haven't explored yet:[^].
