how to force reload?

 [1/6] from: petr:krenzelok:trz:cz at: 18-Oct-2001 15:31


Hi, our provider uses proxy server. In browser, I can force my site to reload, by holding shift key down. I just wonder, if there is any ability to tell rebol's 'read function to reload url, but don't use cached one? Thanks, -pekr-

Not answering your question, but couldn't we make a rebol http server, and reconfigure the browser to request a file from it (all locally)? Then, setting the rebol program to trace/net on, we could see the difference between a normal request from the browser, and a shift-click request from the browser. Anyone know any difficulties with this idea? Anton.

I think there is a rebol proxy on www.rebol.org I was always under the impression that the browser just loads from the local cache based upon whatever criteria, and shift load tells it to ignore the local cache. However, the problem raised is likely how to bypass your ISP's cache. Don't think it can be done. -- Graham Chiu

Yes, I will set it up to see what's the difference ...

Hmm, strange. I visited Cyphre's rebsite, to see what is new. I knew that there is something new, as I looked at his rebsite from my home computer. I pressed right button, and "reload" button. Then I switched to console, and several times tried to read the url. No success though. Then I swithed to Netscape, and - no success too. So I pressed shift + reload (or reload button, don't remember now) and browser displayed updated index.r file finally. That's how I update rebsites nowadays - cut and from browser, finding corresponding index.r file in View local cache, pasting new content :-)) -pekr-

A dodgy way is to add a random query-string to your URL, but how appreciated this is I wouldn't know. (: The proxy thinks it's a new URL each time I guess. Example... read rejoin [url "?" random 10000] Using "if-modified-since" with HTTP's GET is supposed to force a reload if the file's date is later than the date you give, but I haven't found it to work too well. And of course you'd have to write your own tcp routine instead of using 'read.

My other impression is that if you request enough times, the ISP's caching software goes to look if there is an updated version and brings it down for you :) -- Graham Chiu
