[Javascript] JavaScritpt simple compression code

[Allard Schripsema]

Hi there

First of all i?d like to ask you if you are concatenating (using a loop) to
get these big strings
like for (...) {strchunk =getChunk() ; strtotal = strtotal + strchunk }

If this is the case, this probably is your big performance problem, NOT the
sending of these strings. (even 50 querystrings = 100 tcp packets * 20 ms???
NOT a "big" deal)
The answer would be to avoid concatenating into the big string until the
latest possible moment

If you?re after some simple compression tecnique, check out the .pcx
(imageformat) compression.
Or we could invent something here in this group, if you want.

great problem!

Hi Matt.

Testing with IE, I found that I can send URLs of less than 2000
characters. So I split original string in 1900 length parts (I don't
like to reach the exact limit).

The largest string I have found is about 200.000 characters.
Fornutatly, normally they are about 1000-5000 (sometimes I only GET
one time).

Don't mind for strings larger than 200.000. This is a very specific
scenary and I can create a rule for not sending strings larger than
250.000, for example.

In response to POST vs GET, I found that with default IE configuration
user gets a security message when trying to submit the hidden form.
That's why I disagree with POST.
