URL size

[UKuser]

Hi,

I have a page where multiple fields can be edited:

Name Age DOB
[name1] [age1] [dob1]
[name2] [age2] [dob2]
[name3] [age3] [dob3]
[name4] [age4] [dob4]
[name5] [age5] [dob5]

Where you can type in any of the fields etc and with one click all
these get updated by Javascript concatenating them into one variable,
escaped and passed through GET.

However I've discovered that when there are LOTS of entries, I have a
problem - I.E. seems to restrict the length of a URL to 2KB whereas FF
appears to be much higher.

Is there an alternative way to somehow send this data to my PHP
script? Would POST face the same restrictions and is it better/worse
than using GET for AJAX?

Thanks

A

Google for `IE OR "Internet Explorer" URL length'.

script?
Yes.

No.

and is it better/worse than using GET for AJAX?

No.

Correct:

whereas FF appears to be much higher.

Yes it is, but the official recommendation says:

| Servers should be cautious about depending on URI lengths above
| 255 bytes, because some older client or proxy implementations
| may not properly support these lengths.

script?

Yes, by using POST.

I don't believe POST has a limit on request size; but web server and/
or application may set their own rules. You can send both GET and POST
requests in AJAX.

Hope this helps,

Thanks to both replies. I did a quick bit of investigating and looks
like POST is the way to go!! Thanks A
