Not able to pass long string to CGI callout

Hi,

My Problem is i am not able to pass a relatively long string to CGI. When i trying to pass the string as a parameter to CGI call, it is truncating the string.

Is there is any limit on to string lenght passed as argument ?
If so how can i overcome this problem ?

My Call is something like this :
********************************

var url="http://"+ server +"/iw-bin/html/checkhtml.pl?sendString="+sendString;

window.open(url,'ValidateHTML','resizable=1,width=500,height=600,scrollbars=yes');

********************************

Are you finding any problem with the way CGI callout has been called ??

Please suggest me any alternative if any ??

Thanks a Million in advance..!

Pavi

Hi Praveen,

You can write the string in a file and send that file name as a key value pair to the URL.

For eg:-

urlToOpen = fileToOpen.cgi?filename="+fileName;
where fileName is the name of the file where you have written the string and in the cgi,you can retrieve the name by using form varibale filename.
window.open(urlToOpen,'winName',''height=400,width=600,resizable=yes');

Thanks,
Natasha.

It's not so much the string length as total URL length.

SGML spec declares that a URL as an attribute value cannot be longer than 1024 characters (in reality it's implementation dependent).
Similarly, the GET request is stored in the server variable QUERY_STRING, which can have it's own limitations in certain scenarios

And how exactly would you write a File using Java Script? Even more interesting, JS is running on the Client Side Browser.
How would you propose to write a File that Web Server would have an access to?

For that matter,we can use the call server method and pass the third parameter as false which means the parameters are being sent through POST method which has no such limitation on the length of the string.

callServer("http://"+server+"/iw-bin/fileName.cgi",inputParam,false);

Ok. What does it have to do to Pummy's request though? (S)he wanted to render a Page, not call Server Script.
Besides, you are making an assumption that all these is going on DCR's FormAPI. Nothing of a sort has been indicated

Hi Praveen,

Can you plz elabolrate your requirement and the issue you are facing so that suggestions/solution could be provided as per your requirement not per my assumptions.

Thanks,

Hi Natasha/ISCBorisB;

Yes your assumptions are nearly perfect to my requirements.My Requirement is some thing like this.

1. Need to validate HTML source which is being entered in a VF Item.
2. On save event anything entered in VF Item (HTML Source) needs to be validated. And set back to Item.(Ex: every <b> tag needs to be replaced with <strong> )
3. Though i can do this using Javascript for simple validations.. my client wants this to be implemented as CGI with user interaction.

The Solution i had started looking is some thing like this.

1. Pass the VF Source to CGI call server.
2. After validating pass the HTML String back to DCR call back function.

But i faced problem passing relatively long string (above 1024 chars) as suggested by POST method implementation.

Natash,
I agree to your point that i can write the string into Temp File and read that back in my callout CGI. But.. Mean time i also need to access the validated html source(say i have written the validated source to new file).. how do i go about retrieing value back in to DCR form ??

Please suggest me more on to this.

Thanks a lot for all your earlier feedbacks..
