form upload limit
Hello, I didn't find anywhere in Net how much is browser form upload limit (with POST) and how much is Apache's default form data access(input) limit. If anyone knows where I can find this data i'd be grateful. I tested this form upload with large text and in my case only 64K went thru (ended up in MySQL). I saw in Apache homepage, that I could define POST_MAX like this: my $apr = Apache::Request-new($r, POST_MAX = 1024); Err, is this 1024 bytes or kbytes? (OT - Perl basics question) Right now I define $apr this way: $apr = Apache::Request-new( $r-is_main ? $r : $r-main ); Now how I tell $apr that its POST_MAX = 1024? Rgds, Viljo

If anyone knows where I can find this data i'd be grateful. There is no such a limit in Apache and probably most browsers. The limit can be the amount of available RAM (if the file is aggregated in the memory) or the filesystem limits (not enough disk space, if the uploaded file is created on the filesystem). You can limit it within your code, though. I tested this form upload with large text and in my case only 64K went thru (ended up in MySQL). I saw in Apache homepage, that I could define POST_MAX like this: my $apr = Apache::Request-new($r, POST_MAX = 1024); Err, is this 1024 bytes or kbytes? Since CGI.pm is the base of Apache::Request (but written in Perl, whereas Apache::Request is written mostly in C), parts of CGI.pm's extensive documentation will apply for Apache::Request as well. So if you look at CGI.pm's manpage you will see that it's in bytes: $CGI::POST_MAX If set to a non-negative integer, this variable puts a ceiling on the size of POSTings, in *bytes*. If CGI.pm detects a POST that is greater than the ceiling, it will immediately exit with an error message. This value will affect both ordinary POSTs and multipart POSTs, meaning that it limits the maximum size of file uploads as well. You should set this to a reasonably high value, such as 1 megabyte. You are welcome to send the documentation patches to the developers of the Apache::Request package at [EMAIL PROTECTED] This kind of contribution helps a lot.

Re: form upload limit
I didn't find anywhere in Net how much is browser form upload limit (with POST) and how much is Apache's default form data access(input) limit. If anyone knows where I can find this data i'd be grateful. Apache's default is 75 and it's under the directive LimitRequestBody 75 From my expirience, it is the lower boud of the size limit (that is Apache size limit seems to overwrite size limit from POST_MAX) As far as POST_MAX... I was using CGI::POST_MAX=1024*100, which would set the max size to 100 kb. It's also defind in CGI.pm hope this helps, Monika I tested this form upload with large text and in my case only 64K went thru (ended up in MySQL). I saw in Apache homepage, that I could define POST_MAX like this: my $apr = Apache::Request-new($r, POST_MAX = 1024); Err, is this 1024 bytes or kbytes?

Re: form upload limit
There is no such a limit in Apache and probably most browsers. By default, LimitRequestBody is 0 (unlimited) in Apache. We limit incoming requests with this directive, so server resources aren't consumed by excessive. I think POST_MAX happens after the request is already read into memory. LimitXMLRequestBody has a default limit of 100. There are other LimitRequest* directives which limit various aspects of the header. Rob

You can limit it within your code, though. About one third requests going through proxies. And about 70% of proxies are Squids. And nearly all Squids has default upload limit of 1M. Igor Sysoev
Re: form upload limit
Joe Schaefer [EMAIL PROTECTED] said something to this effect on 12/13/2001:
Is this what you want
$apr = Apache::Request-new( $r-is_main ? $r : $r-main,
POST_MAX = 1024);
? I don't think Apache::Request provides any Perl methods for
culling the post_max setting from a $apr; you'd either have to
write some XS for that, keep track of it yourself, or lobby for
a new feature ;)
Or you can patch libapreq-0.33/Request/Request.xs:
*** Request.xs.orig Thu Dec 13 11:44:25 2001
--- Request.xs Thu Dec 13 11:36:06 2001
***
*** 356,361
--- 356,375
Apache::Request req
int
+ ApacheRequest_post_max(req, max=Nullsv)
+ Apache::Request req
+ SV *max;
+
+ CODE:
+ if (max != Nullsv) {
+ req-post_max = (int)SvIV(max);
+ }
+ RETVAL = req-post_max;
+
+ OUTPUT:
+ RETVAL
+
+ int
ApacheRequest_parse(req)
Apache::Request req
This will add $apr-post_max, which works in my (simplistic and
deterministic) tests.
