Request.QueryString Limitations?

[Picho]

Hi everyone.

I have a webForm that gets input using the querystring , builds an image
according to the input and therefor renders an image as a contentType/GIF in
the output stream.

I use this webForm as the imageUrl of an image control on another page.

the problem is that some of the bitmaps i have to render has a lot of data
that goes into the queryString. seems like the rendered HTML (from the ASPX
page) that has the image control and the imageUrl attribute is doing a good
job. the image is not displayed (only in the "large data" images). when i
copy this url and paste it at the addres bar it shows up ok.

my guess is that the url string gets split/chopped/hell knows what.

any suggestions?

thanx,

Picho

its something like 2048 characters permitted in the url.

And any old proxy in-between may limit the query string even more and chop
it off... yes, do POST.
