    Form behind The Proxy Server

    Asked by Sohail Ahmed on February 21, 2011 at 06:20 AM

    Hi,

    We are using ISA 2006 and Websense in our organazition, current problem we are having is, when we create a form or edit the form the changes take so much time to effect, some times it takes two days or some times it takes a week for a changes to take effect, we have added jotform.com and cdn.jotfor.ms in websense to exclude these sites from filtering.

    Can you advise if is there any thing else I need to exclude/add  from the list?

    PS: Without the proxy server all works fine.

    Thanks
    Sohail

    Hi Sohail,

    If you are embedding the form in another page then there are a couple of things you could try.  First would be to set a cache-control or pragma meta tag in the page itself.  Have a look at this link to see how to do that:

    http://www.i18nguy.com/markup/metatags.html

    Meta tags wont always work for upstream proxies so the next thing to try would be to modify the page address somehow.  For example, you could append a question mark with some random number, something like the following:

    http://www.jotform.com/form/10443843655/?1

    The number 1 at the end of the url effectivy makes the proxy think it's being asked for a new page.  This technique should also work for iframes.  Please do get back to me if you are still having problems.

    Thanks

    Thanks for the respose  Daniel,

    I tested the /?1 option but it hasn't made any difference but in regards cache control settings, I am not sure what I am looking at, as I am not into web languages. Could You please guide me that if I am in the form (settings) what do I need to do in order to disable cache control.

    Thanks

    Hi Sohail,

    I'm sorry, but it's not possible to affect caching settings by using the form builder, since caching is something that happens for the entire document, rather than just a form (i.e. a piece of the document or page).  If you want to try to modify cache settings then you'll have to edit your page by including a meta tag in the head of the page itelself. See this example,

    <META HTTP-EQUIV="Pragma" CONTENT="no-cache">

    This goes into the <head> section of your webpage.  If you'd like to let me know which form it is please send the address and I can take a look at your page, and maybe guide you better.
