HTTP message size limit?

Hello everyone,

IM facing a problem with Http connections that I can't find a way to it.

Im making a HTTP POST request to a web service, where all content type is JSON. This JSON contains, among other things a binary file (represented by an array of integers). Example:

{
"SessionId':"string content. "
"OutputFile": {}
"Binary": [81,
109,
70,

....],
"FileName':"string content. "
'Size': 250
}
}

The size of the JSON data is closely depends on the size of the file. When the file is 'big' (as the 20 KB or more) the JSON Gets a size that cannot be sent and shows me a HTTP 400 response code. But if the file is about 15 KB or less, size JSON its 'ok' and the web service called without problem.

So my question is: is there a size limit in a http body when you make a POST to a web service? I have this problem in emulator and device (8520 OS and 5.0).

I try searching the forum for help, but there is no answers to concrete the size of an HTTP POST. I found a few discussions that talk about the multipart post method, but I think that it helped me (my web service expects a JSON well formed in the body of the request).

Thank you in advance, I really need your help!

Good bye.

I finally found a workaround for this problem.

After implementation al the setting maxSize..., maxBuffer..., readersQuota, etc., that I found in the web.config file and still not achieved nothing, I decided to change my .net 3.5 WS. The only thing different between them is the definition in the web.config file.

After you make this change, now I can connect to the other side.

Probably there are some settings that I could not understand in .net 4.0, but since it is not critical for my project, I made the change and it works.

Thanks everyone for the help!

Good bye.

    42117958, the message size exceeds the size limit
    31457280 Server 63.127.11.31 [63.127.11.31]

    You try to send a 42 MB file, your server only allows you to send 31 megabytes and beneficiaries are limited to 10 megabytes.  Try using Irfanview (www.irfanview.com - free) and you can resize them and save as jpg files and they will be 100 X smaller.  Otherwise, send them 1 by 1.

    To resize them you can specify an image to about 640 x 480 pixels (or the beach), and that will keep the size appropriate for the email.

  • Exchange 2007 SP3 increase in message size does not work why?

    I have a windows server 2008R2 with Exchange 2007 SP3, currently the maximum to send and receive message size is 30 MB. My MD needs to send an email which is 60 MB.

    I went through and changed all the parameters in which I expect to do. If I run best practices, it signals that the Send connectors and the receiver are high at 60 MB. Fine, I said.

    I open Microsoft Outlook 2007 and try to attach several files to 5 MB per element. Outlook has that attachments are great when I get to 29 MB.

    This is only a temporary job, so not worried, but can, my concern is what's wrong.

    We had Exchange 2007 running on windows 2008R2 who say it cannot be done while we had a server crash. I had to transfer exchange on a temp server. I've migrated on the main server which is brand new but this time, I installed Excahnge 2007SP3. I don't know if this migration has nothing to do with it.

    Any help would be great

  • Outlook 2007 is limitation of message size, although there is no restriction of message on the Exchange 2003 server.

    When one of my users trying to reach a 50 MB file to an e-mail message, Outlook 2007 immediately appears with the following message: the attachment size exceeds the allowable limit.  The user is not even allowed to attach the file such as Outlook it immediately blocked.  We have a 10 MB limit for messages that leave the organization.  This user has attempted to send the file to another Member of our Organization. In Outlook 2003, we are able to send 50 MB files to another without problem. Does anyone have any suggestions? I wonder if there is a setting in Outlook 07 which limits the size of an attachment. The confusing part is that he was not yet able to attach the file.

    Hello

    1 you need to set the maxRequestLength value in the web.config file to a value greater than 50 MB. The maxRequestLength value in the web.config file is a parameter ASP.NET prevents applications greater than a certain length that has been added to prevent DOS attacks. He is set to 30 MB by default and must be increased in order to send attachments more than 30 MB. This could also be declined to enforce a lower limit.

    2. you need to increase the MaxSubmitMessageSize which is a property of the mailbox of readonly (MaxSubmitMessageSize = 0x666D0003) and this is where we reach the limit of 10 MB.

    It is read from the following locations:

    1. First reading of the object the user mailbox
    2. If not found as indicated by "unlimited", Transport Settings Container
    3. If not found as indicated by "unlimited", Org (read default Org container) container

    To set the value, use the following tasks in the Exchange Management Shell:

    1 set-transportconfig MaxSendSize (this is KBS) and then assign 51200 for 50 MB attachments. This will put it to all users

    Or

    2 set-mailbox and set the MaxSendSize (this is KBS) to 51 200 for attachments of 50 MB forspecific to a set of users.

    Once you set or the other, you must recycle store or not access to the mailbox for 15-20 minutes (to allow to store the cache expire) so that the change in size to have effect. In addition, the property is stored in AD and submitted to replication delays.

    One last thing that you should be aware of (sorry, the list will just):

    We have a timeout of 60 minutes for any attachment request or download attachment query (in OWA basic and Premium). So if you try to download an attachment 50 MB on a 56 Kbps connection, you will then expire and get a HttpWebException (e.g., the max upload is about 25 MB on a 56 Kbps connection).

    So, to sum up, there are two keys to send a large attachment:

    1 ASP.NET change web.config settings.

    2 modify the MaxSendSize using the set-TransportConfig (for all users) or Set-Mailbox for individual users.

    And you must

    3 ensure that the total download time will be less than 60 minutes (depending on your size and the speed of your network link)

    The web.config change is immediate, but the MaxSendSize change takes time, because of the caching strategy (the letter box, DSAccess deadlines and delays in replication cache).

    Examples:

    Changes to Web.Config

    By default, web.config under OWA virtual directory (Microsoft\Exchange Server\ClientAccess\Owa) will have the following entry (by default, the maximum request size is about 30 MB):

    ....

    Change to where X is the value you want in KBs. 50 MB, X will be of approximately50000

    Change the size limit of messages by user

    Go in the Exchange Management Shell and type the following command:

    Set-mailbox - id: "username" - MaxSendSize:50000

    Where "username" is the identity of the mailbox. This will set the limit to send message to about 50 MB. You need to restart the store to see the effect immediately.

    Change the size limit for messages of all users

    Go in the Exchange Management Shell and type the following command:

    -Set-transportconfig MaxSendSize: 50000

    This will set the limit to send message to about 50 MB. You need to restart the store to see the effect immediately.

  • WARNING: table size limit exceeded

    What it means?

    errorMessage: warning Table size limit exceeded by GIS 5378.0. Additional table will be created. name = errUnclassified

    These warnings are initially simply information and do not constitute an error that the user needs to worry.

    When signatures are added to the sensor, the sensor will compile all signatures in a large regular expression cache table. This considerably speeds up the analysis. The cache table, however, has a limited size. When you add a signature to the cache table would develop the table beyond the allowed size, then you will see the warning that you posted above.

    That caveat lets you know, it's that he couldn't add that signature to the existing table, and so it must create a new table for the signature and the signatures follow.

    This information before debugging for developers of signature just so they can track what is happening because signatures are added.

    The sensor works correctly and work very well. The addition of the new table only adds a very small performance reduction as an extra table must be analyzed during the analysis of the packets.

    Users running with the signature by default settings would never need to worry about this message and can consider only a few logging information (it should really have been a status message instead of an error message)

    Users who are unretiring signatures or creating their own custom signatures can see this message as they set up their sensors. So then he os to let them know that tables additional cache is taken to be created to manage the additional signatures. Once more just information and not a real error.

  • PE9 Panorama - size limit?

    I have just started juggling the panorama functions in PE9. I have a set of 13 pictures of the Valley of death I am developing. If I try to make all 13 I get a message that it cannot do because some photos may not be aligned. Yet this seems in fact be an alignment problem, I did do it in sections. It will work 1 fine pictures that merge-11, but can not do 1-12. But there is nothing inherently wrong with 12 such that it will merge with happiness, for example, 7-13. Am I encountering some kind of size limit of that width (11 photo fusion is more than 28000 pixels wide and is 49 inches wide), either in terms of pixels or just total? Have been totally unable to find an indication of size limits online.

    Have not worked with that many, so may have missed something obvious. Help, please.

    Nancy

    Photoshop elements has a limit size of pixel of 30, 000 x 30, 000 if the size of

    your pano would likely exceed these dimensions vertically or horizontally

    and that's why things won't complete the merge of photo.

    Try to reduce the size in pixels of each photo about half, save them as 8-bit targets

    and see if that makes a difference.
