Pretty simple question: which one of these two PHP (version 5+) header call is the "best"? header('Not Modified', true, 304); header('HTTP/1.1 304 Not Modified'); I'm pretty sure the first one is the most polyvalent one, but just curious if PHP would "fix" the second one if under HTTP 1.0... Thanks! Edit: One of these header crashes...
I have cacheable dynamic content made in PHP 5.1.0+. I already send the correct headers (including Last-Modified and ETag) to clients. I now want my script to be able to answer $_SERVER['HTTP_IF_MODIFIED_SINCE'] and $_SERVER['HTTP_IF_NONE_MATCH'] when present. When the conditions matches, I want to answer a HTTP 304 "Not Modified" to cl...
I have a php script that generates a pdf report. When we go to save the pdf document, the filename that Acrobat suggests is report_pdf, since the php script is named report_pdf.php. I would like to dynamically name the pdf file, so I don't have to type the appropriate name for the report each time that I save it. Asking on a news group...
Hi, I am building facebook app using iFrame (using Google App Engine Java,JSP and Facebook-api-java), and when Facebook calls back to my website, I expect to get the fb_sig_* request params for the iFrame, but I get those params in HTTP referer header instead. When I use the php client, i get the fb_sig_* in the $[_GET] as expected. W...
After searching a lot, reading every tutorials I've found and asking some questions here, I've finally managed to answer corrctly (at least I think) to if-none-match and if-modified-since HTTP requests. To do a quick recap, this is what I do on every pages cacheable: session_cache_limiter('public'); //Cache on clients and proxies sessi...
I would like to not cache my aspx pages anywhere.

I am working on my and I am struggling to work out how to send PUT and DELETE arguments in PHP. In a few places I have seen people using the options: $this->option(CURLOPT_PUT, TRUE); $this->option(CURLOPT_POSTFIELDS, $params); Annoyingly, this seems to do nothing. Is this the correct way to set PUT parameters? If so, how do I set ...
Is there a particular order in PHP to set HTTP headers with the header() function ? I mean for example must I call header('Content-Language: en'); before header('Content-Type: text/plain'); or whathever order will be OK. My guess is that order isn't important as long as all he headers are set before any content outputted, but I just wa...
If you look at the PHP doc help for function session_cache_limiter(), you will see that if the cache_limiter parameter is set to private or nocache the Expires HTTP header is set to a const date (Thu, 19 Nov 1981 08:52:00 GMT). I understand that this is a date in the past to avoid caching, but why this date/time in particular? It's not t...

Can anyone tell me how to explicitly turn off or leave the HTTP_REFERER header blank? Thanks in advan...
